general description the max4800/max4801/max4802 provide high-volt-age switching on eight channels for ultrasonic imaging and printer applications. the devices utilize bcdmos process technology to provide eight high-voltage low- charge-injection spst switches, controlled by a digital interface. data is clocked into an internal 8-bit shift reg- ister 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 /v nn = +100v/-100v, +185v/-15v, and +40v/-160v. the digitalinterface 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 v dd supply voltage. the max4802 provides integrated 35k bleed resistors on each switch terminal to discharge capaci-tive 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, and 28- pin plcc 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 0? to +70? temperature range. applications ultrasound imagingprinters features ? pin-compatible replacement for supertex hv20220 (max4800) ? pin-compatible replacement for supertex hv20320 (max4801) ? pin-compatible replacement for supertex hv232 (max4802) ? flexible high-voltage supplies up to v pp - v nn = 200v ? low-charge injection, low-capacitance 22 switches ? dc to 10mhz analog-signal frequency range ? -77db off isolation at 5mhz ? low 10 a quiescent current ? integrated bleed resistors (max4802) ? available in plcc, tqfp, and csbga packages max4800/max4801/max4802 low-charge injection, 8-channel, high-voltage analog switches ___________________________________________________ _____________ maxim integrated products 1 19-0631; rev 2; 5/09 for pricing, delivery, and ordering information, please contact maxim direct at 1-888-629-4642, or visit maxim? website at www.maxim-ic.com. ordering information/selector guide part bleed resistors second source pin-package ma4800 ccm no hv20220fg 48 tqfp MAX4800CQI no hv20220pj 28 plcc max4800cxz no hv220** 26 csbga ma4801 cqi no hv20320pj 28 plcc ma4802 ccm yes hv232fg 48 tqfp max4802cqi yes hv232pj 28 plcc max4802cxz yes hv230ga 26 csbga note: all devices are specified over the commercial 0? to +70? temperature range. ** not pin-for-pin compatible. downloaded from: http:///

max4800/max4801/max4802 low-charge injection, 8-channel, high-voltage analog switches 10 _________________________________________________ _____________________________________ when v nn is connected to gnd (single-supply applica- tions), the devices operate with v pp up to +200v. the v pp and v nn high-voltage supplies are not required to be symmetrical, but the voltage difference v pp - v nn must not exceed 200v. bleed resistors (max4802) the max4802 features integrated 35k bleed resistors to discharge capacitive loads such as piezoelectrictransducers. each analog switch terminal is connected to rgnd with a bleed resistor. serial interface the max4800/max4801/max4802 are controlled by aserial 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). 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. toreduce noise due to clock feedthrough, drive le logic- high while data is clocked into the shift register. afterthe 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 clearinput. 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 intothe latch. power-on reset the max4800/max4801/max4802 feature a power-onreset circuit to ensure all switches are open at power- on. the internal 8-bit serial shift register and latch are set to zero on power-up. le clk dout data from previous data byte power-up default: d7-d0 = 0 d7 d6 d5 d4 d3 d2 d1 d0 d7 din d7 d6 d5 d4 d3 d2 d1 d0 msb lsb figure 2. latch enable interface timing downloaded from: http:///
