+3V to +5.5V, 1Microamp, 250kbps, EIA/TIA-562, EIA/TIA-232 Transmitters/Receivers
The Intersil ISL8563 contains 3.0V to 5.5V powered transmitters/receivers which meet ElA/TIA-562 and ElA/TIA-232 specifications, even at VCC = 3.0V. Targeted applications are PDAs, Palmtops, and notebook and laptop computers where the low operational, and even lower standby, power consumption is critical. Efficient on-chip charge pumps, coupled with a manual powerdown function, reduce the standby supply current to a 1A trickle. Small footprint packaging, and the use of small, low value capacitors ensure board space savings as well. Data rates greater than 250kbps are guaranteed at worst case load conditions. The ISL8563 is fully compatible with 3.3V only systems, mixed 3.3V and 5.0V systems, and 5.0V only systems. This product features an improved charge pump which delivers 5V transmitter supplies, allowing the use of the ISL8563 in RS-562 and RS-232 applications. RS-562 applications will benefit from the improved noise immunity afforded by the 5V output swing capability. Table 1 summarizes the features of the device represented by this data sheet, while Application Note AN9863 summarizes the features of each device comprising the 3V RS-232 family. For a drop-in compatible part with 15kV ESD protection, please see the ISL8563E data sheet.

ISL8563 Detailed Description
The ISL8563 operates from a single +3V to +5.5V supply, guarantees a 250kbps minimum data rate, requires only four small external 0.1F capacitors, features low power consumption, and meets all ElA/TIA-562 and EIA/TIA-232 specifications. The circuit is divided into three sections: The charge pump, the transmitters, and the receivers. (VCC = 0V). The receivers' Schmitt trigger input stage uses hysteresis (even in powerdown) to increase noise immunity and decrease errors due to slow input signal transitions. The ISL8563 inverting receivers disable only when EN is driven high. Standard receivers driving powered down peripherals must be disabled to prevent current flow through the peripheral's protection diodes (see Figures 4 and 5).

Charge-Pump
Intersil's new ISL8563 utilizes regulated on-chip dual charge pumps as voltage doublers, and voltage inverters to generate 5.5V transmitter supplies from a VCC supply as low as 3.0V. This allows these devices to maintain RS-232 compliant output levels over the 10% tolerance range of 3.3V powered systems. The efficient on-chip power supplies require only four small, external 0.1F capacitors for the voltage doubler and inverter functions over the full VCC range. The charge pumps operate discontinuously (i.e., they turn off as soon as the V+ and V- supplies are pumped up to the nominal values), resulting in significant power savings.
FIGURE 3. INVERTING RECEIVER CONNECTIONS
Powerdown Functionality
This 3V device requires a nominal supply current of 0.3mA during normal operation (not in powerdown mode). This is considerably less than the 5mA to 11mA current required by 5V devices. The already low current requirement drops significantly when the device enters powerdown mode. In powerdown, supply current drops to 1A, because the onchip charge pump turns off (V+ collapses to V CC, Vcollapses to GND), the transmitter outputs three-state, and the transmitter input pull-ups disable. This micro-power mode makes the ISL8563 ideal for battery powered and portable applications.
Transmitters
The transmitters are proprietary, low dropout, inverting drivers that translate TTL/CMOS inputs to EIA/TIA-562/232 output levels. Coupled with the on-chip 5.5V supplies, these transmitters deliver true RS-562/232 levels over a wide range of single supply system voltages. All transmitter outputs disable and assume a high impedance state when the device enters the powerdown mode (see Table 2). These outputs may be driven to 12V when disabled. All devices guarantee a 250kbps data rate (VOUT = 5V) for full load conditions (3k and 1000pF), VCC 3.0V, with one transmitter operating at full speed. Under more typical conditions of V CC 3.3V, RL = 3k, and CL = 250pF, one transmitter easily operates at 900kbps. Unused transmitter inputs may be left unconnected because they will be pulled to VCC by the on-chip pull-up resistors. Forcing the ISL8563 into power down disables the pull-up resistors to further minimize power.
Software Controlled (Manual) Powerdown
The ISL8563, is forced into its low power, stand by state via a simple shutdown (SHDN) pin. Driving this pin high enables normal operation, while driving it low forces the IC into its powerdown state. Connect SHDN to VCC if the powerdown function isn't needed. Note that all the receiver outputs remain enabled during shutdown (see Table 2). For the lowest power consumption during powerdown, the receivers should also be disabled by driving the EN input high (see next section, and Figures 4 and 5). The time required to exit powerdown, and resume transmission is less than 30s.
Receiver ENABLE Control
The device also features an EN input to control the receiver outputs. Driving EN high disables all the receiver outputs placing them in a high impedance state. This is useful to eliminate supply current, due to a receiver output forward biasing the protection diode, when driving the input of a powered down (VCC = GND) peripheral (see Figure 4). The enable input has no effect on transmitters.
Receivers
The ISL8563 contains standard inverting receivers that three-state via the EN control line. All the receivers convert RS-562/232 signals to CMOS output levels and accept inputs up to 25V while presenting the required 3k to 7k input impedance (see Figure 3) even if the power is off

Transmitter Outputs When Exiting Powerdown
Figure 6 shows the response of two transmitter outputs when exiting powerdown mode. As they activate, the two transmitter outputs properly go to opposite RS-562/232 levels, with no glitching, ringing, nor undesirable transients. Each transmitter is loaded with 3k in parallel with 2500pF. Note that the transmitters enable only when the magnitude of the supplies exceed approximately 3V.

High Data Rates
The ISL8563 maintains the RS-232 5V minimum transmitter output voltages even at high data rates. Figure 7 details a transmitter loopback test circuit, and Figure 8 illustrates the loopback test result at 120kbps. For this test, all transmitters were simultaneously driving RS-232 loads in parallel with 1000pF, at 120kbps. Figure 9 shows the loopback results for a single transmitter driving 1000pF and an RS-232 load at 250kbps. The static transmitters were also loaded with an RS-232 receiver.

Capacitor Selection
The charge pumps operate with 0.1F (or greater) capacitors for 3.0V VCC 5.5V. Increasing the capacitor values (by a factor of 2) reduces ripple on the transmitter outputs and slightly reduces power consumption. C2, C3, and C4 can be increased without increasing C1's value, however, do not increase C1 without also increasing C2, C3, and C4 to maintain the proper ratios (C1 to the other capacitors). When using minimum required capacitor values, make sure that capacitor values do not degrade excessively with temperature. If in doubt, use capacitors with a larger nominal value. The capacitor's equivalent series resistance (ESR) usually rises at low temperatures and it influences the amount of ripple on V+ and V-.
Power Supply Decoupling
In most circumstances a 0.1F bypass capacitor is adequate. In applications that are particularly sensitive to power supply noise, decouple VCC to ground with a capacitor of the same value as the charge-pump capacitor C1. Connect the bypass capacitor as close as possible to the IC.
