19-0631; Rev 1; 3/07 Low-Charge Injection, 8-Channel, High-Voltage Analog Switches General Description The MAX4800/MAX4801/MAX4802 provide high-voltage switching on eight channels for ultrasonic imaging and printer applications. The devices utilize BCDMOS process technology to provide eight high-voltage lowcharge-injection SPST switches, controlled by a digital interface. Data is clocked into an internal 8-bit shift register and retained by a programmable latch with enable and clear inputs. A power-on reset function ensures that all switches are open on power-up. The MAX4800/MAX4801/MAX4802 operate with a wide range of high-voltage supplies including: VPP/VNN = +100V/-100V, +185V/-15V, and +40V/-160V. The digital interface operates from a separate V DD supply from +2.7V to +13.2V. Digital inputs DIN, CLK, LE, and CLR are +13.2V tolerant, independent of the VDD supply voltage. The MAX4802 provides integrated 35k bleed resistors on each switch terminal to discharge capacitive loads. The MAX4800 and MAX4802 are drop-in replacements for the Supertex HV20220 and HV232. The devices are available in the 48-pin TQFP, 26-bump CSBGA, 28-pin PLCC, and 48-pin TQFN packages. The MAX4801 is a drop-in replacement for the Supertex HV20320 and is available in the 28-pin PLCC package. All devices are specified for the commercial 0C to +70C temperature range.

Serial Interface Timing Detailed Description The MAX4800/MAX4801/MAX4802 provide high-voltage switching on eight channels for ultrasound imaging and printer applications. The devices utilize BCDMOS process technology to provide eight high-voltage lowcharge-injection SPST switches, controlled by a digital interface. Data is clocked into an internal 8-bit shift register and retained by a programmable latch with enable and clear inputs. A power-on reset function ensures that all switches are open on power-up. The MAX4800/MAX4801/MAX4802 operate with a wide range of high-voltage supplies including: V PP/VNN = +100V/-100V, +185V/-15V, or +40V/-160V. The digital interface operates from a separate VDD supply from +2.7V to +13.2V. Digital inputs DIN, CLK, LE, and CLR are +13.2V tolerant, independent of the VDD supply voltage. The MAX4802 provides integrated 35k bleed resistors on each switch terminal to discharge capacitive loads. The MAX4800 and MAX4802 are drop-in replacements for the Supertex HV20220 and HV232, respectively. The MAX4801 is a drop-in replacement for the Supertex HV20320. Analog Switch The MAX4800/MAX4801/MAX4802 allow a peak-topeak analog signal range from VNN + 10V to VPP - 10V. Analog switch inputs must be unconnected, or satisfy V NN (V COM_ , V NO_ ) V PP during power-up and power-down. High-Voltage Supplies The MAX4800/MAX4801/MAX4802 allow a wide range of high-voltage supplies. The devices operate with VNN from -160V to -15V and VPP from +40V to VNN + 200V. 9 _______________________________________________________________________________________ Low-Charge Injection, 8-Channel, High-Voltage Analog Switches MAX4800/MAX4801/MAX4802 LE CLK DIN D7 MSB D6 D5 D4 D3 D2 D1 D0 LSB DOUT D7 D6 D5 D4 D3 D2 D1 D0 D7 DATA FROM PREVIOUS DATA BYTE POWER-UP DEFAULT: D7-D0 = 0 Figure 2. Latch Enable Interface Timing When VNN is connected to GND (single-supply applications), the devices operate with VPP up to +200V. The VPP and VNN high-voltage supplies are not required to be symmetrical, but the voltage difference VPP - VNN must not exceed 200V. Bleed Resistors (MAX4802) The MAX4802 features integrated 35k bleed resistors to discharge capacitive loads such as piezoelectric transducers. Each analog switch terminal is connected to RGND with a bleed resistor. Latch Enable (LE) Drive LE logic-low to change the contents of the latch and update the state of the high-voltage switches (Figure 2). Drive LE logic-high to freeze the contents of the latch and prevent changes to the switch states. To reduce noise due to clock feedthrough, drive LE logichigh while data is clocked into the shift register. After the data shift register is loaded with valid data, pulse LE logic-low to load the contents of the shift register into the latch. Latch Clear (CLR) The MAX4800/MAX4801/MAX4802 feature a latch clear input. Drive CLR logic-high to reset the contents of the latch to zero and open all switches. CLR does not affect the contents of the data shift register. Pulse LE logic-low to reload the contents of the shift register into the latch. Power-On Reset The MAX4800/MAX4801/MAX4802 feature a power-on reset circuit to ensure all switches are open at poweron. The internal 8-bit serial shift register and latch are set to zero on power-up. Serial Interface The MAX4800/MAX4801/MAX4802 are controlled by a serial interface with an 8-bit serial shift register and transparent latch. Each of the eight data bits controls a single analog switch (see Table 1). Data on DIN is clocked with the most significant bit (MSB) first into the shift register on the rising edge of CLK. Data is clocked out of the shift register onto DOUT on the rising edge of CLK. DOUT reflects the status of DIN, delayed by eight clock cycles (see Figures 1 and 2). 10 ______________________________________________________________________________________ Low-Charge Injection, 8-Channel, High-Voltage Analog Switches MAX4800/MAX4801/MAX4802 Table 1.

Supply Sequencing and Bypassing The MAX4800/MAX4801/MAX4802 do not require special sequencing of the VDD, VPP, and VNN supply voltages; however, analog switch inputs must be unconnected, or satisfy VNN (VCOM_, VNO_) VPP during power-up and power-down. Bypass VDD, VNN, and VPP to GND with a 0.1F ceramic capacitor as close to the device as possible. Daisy Chaining Multiple Devices Digital output DOUT is provided to allow the connection of multiple MAX4800/MAX4801/MAX4802 devices by daisy chaining (Figure 3). Connect each DOUT to the DIN of the subsequent device in the chain. Connect CLK, LE, and CLR inputs of all devices, and drive LE logic-low to update all devices simultaneously. Drive CLR high to open all the switches simultaneously. Additional shift registers may be included anywhere in series with the MAX4800/MAX4801/MAX4802 data chain. Exposed Paddle The MAX4800 and MAX4802 provide an exposed paddle for improved thermal performance in the TQFN package. Connect the exposed paddle to VNN.
