Ultra Low ON-Resistance, Low Voltage, Single Supply, Dual SPDT Analog Switch
The Intersil ISL84684 device is a low ON-resistance, low voltage, bidirectional, dual single-pole/double-throw (SPDT) analog switch designed to operate from a single +1.65V to +3.6V supply. Targeted applications include battery powered equipment that benefits from low rON (0.35) and fast switching speeds (tON = 50ns, tOFF = 27ns). The digital logic input is 1.8V logic-compatible when using a single +3V supply. Cell phones, for example, often face ASIC functionality limitations. The number of analog input or GPIO pins may be limited and digital geometries are not well suited to analog switch performance. This part may be used to "mux-in" additional functionality while reducing ASIC design risk. The ISL84684 is offered in small form factor packages, alleviating board space limitations. The ISL84684 is a committed dual single-pole/double-throw (SPDT) that consists of two normally open (NO) and two normally (NC) switches. This configuration can be used as a dual 2-to-1 multiplexer. The ISL84684 is pin compatible with the MAX4684 and MAX4685.

Detailed Description
The ISL84684 is a bidirectional, dual single pole/double throw (SPDT) analog switch that offers precise switching capability from a single 1.65V to 3.6V supply with low ON-resistance (0.35) and high speed operation (tON = 50ns, tOFF = 27ns). The device is especially well suited for portable battery powered equipment due to its low operating supply voltage (1.65V), low power consumption (2.7W max), low leakage currents (60nA max), and its tiny TDFN and MSOP packages. The ultra low ON-resistance and rON flatness provide very low insertion loss and distortion to applications that require signal reproduction.

External V+ Series Resistor
For improved ESD and latch-up immunity, Intersil recommends adding a 100 resistor in series with the V+ power supply pin of the ISL84684 IC (see Figure 8). 6

ISL84684
During an overvoltage transient event, such as occurs during system level IEC 61000 ESD testing, substrate currents can be generated in the IC that can trigger parasitic SCR structures to turn ON, creating a low impedance path from the V+ power supply to ground. This will result in a significant amount of current flow in the IC which can potentially create a latch-up state or permanently damage the IC. The external V+ resistor limits the current during this over-stress situation and has been found to prevent latch-up or destructive damage for many overvoltage transient events. Under normal operation, the sub-microamp IDD current of the IC produces an insignificant voltage drop across the 100 series resistor resulting in no impact to switch operation or performance.

FIGURE 9. OVERVOLTAGE PROTECTION
Supply Sequencing and Overvoltage Protection
With any CMOS device, proper power supply sequencing is required to protect the device from excessive input currents which might permanently damage the IC. All I/O pins contain ESD protection diodes from the pin to V+ and to GND (see Figure 9). To prevent forward biasing these diodes, V+ must be applied before any input signals and the input signal voltages must remain between V+ and GND. If these conditions cannot be guaranteed, then precautions must be implemented to prohibit the current and voltage at the logic pin and signal pins from exceeding the maximum ratings of the switch. The following two methods can be used to provide additional protection to limit the current in the event that the voltage at a signal pin or logic pin goes below ground or above the V+ rail. Logic inputs can easily be protected by adding a 1k resistor in series with the input (see Figure 9). The resistor limits the input current below the threshold that produces permanent damage and the sub-microamp input current produces an insignificant voltage drop during normal operation. This method is not acceptable for the signal path inputs. Adding a series resistor to the switch input defeats the purpose of using a low rON switch. Connecting Schottky diodes to the signal pins as shown in Figure 9 will shunt the fault current to the supply or to ground thereby protecting the switch. These Schottky diodes must be sized to handle the expected fault current.
Power-Supply Considerations
The ISL84684 construction is typical of most single supply CMOS analog switches, in that they have two supply pins: V+ and GND. V+ and GND drive the internal CMOS switches and set their analog voltage limits. Unlike switches with a 4V maximum supply voltage, the ISL84684 5.5V maximum supply voltage provides plenty of room for the 10% tolerance of 4.3V supplies, as well as room for overshoot and noise spikes. The minimum recommended supply voltage is 1.65V. It is important to note that the input signal range, switching times, and ON-resistance degrade at lower supply voltages. Refer to the "Electrical Specification" tables on page 2 and "Typical Performance Curves" on page 9 for details. V+ and GND also power the internal logic and level shiftiers. The level shiftiers convert the input logic levels to switched V+ and GND signals to drive the analog switch gate terminals. This family of switches cannot be operated with bipolar supplies because the input switching point becomes negative in this configuration.
Logic-Level Thresholds
This switch family is 1.8V CMOS compatible (0.5V and 1.4V) over a supply range of 2.7V to 4.5V (see Figure 18). At 2.7V, the VIL level is about 0.53V. This is still above the 1.8V CMOS guaranteed low output minimum level of 0.5V, but noise margin is reduced. The digital input stages draw supply current whenever the digital input voltage is not at one of the supply rails. Driving the digital input signals from GND to V+ with a fast transition time minimizes power dissipation.

High-Frequency Performance
In 50 systems, the ISL84684 has a -3dB bandwidth of 120MHz (see Figure 19). The frequency response is very consistent over a wide V+ range and for varying analog signal levels. An OFF switch acts like a capacitor and passes higher frequencies with less attenuation, resulting in signal feedthrough from a switch's input to its output. Off isolation is the resistance to this feedthrough, while crosstalk indicates the amount of feedthrough from one switch to another. Figure 20 details the high off Isolation and crosstalk rejection provided by this part. At 100kHz, off isolation is about 62dB in 50 systems, decreasing approximately 20dB per decade as frequency increases. Higher load impedances decrease off isolation and crosstalk rejection due to the voltage divider action of the switch OFF impedance and the load impedance.
Leakage Considerations
Reverse ESD protection diodes are internally connected between each analog-signal pin and both V+ and GND. One of these diodes conducts if any analog signal exceeds V+ or GND. Virtually all the analog leakage current comes from the ESD diodes to V+ or GND. Although the ESD diodes on a given signal pin are identical and therefore fairly well balanced, they are reverse biased differently. Each is biased by either V+ or GND and the analog signal. This means their leakages will vary as the signal varies. The difference in the two diode leakages to the V+ and GND pins constitutes the analog-signal-path leakage current. All analog leakage current flows between each pin and one of the supply terminals, not to the other switch terminal. This is why both sides of a given switch can show leakage currents of the same or opposite polarity. There is no connection between the analog signal paths and V+ or GND.
