General Description

The MAX4800A/MAX4802A provide high-voltage switch-

ing 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 20MHz serial

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 devices operate with a wide range of high-voltage

and +40V/-160V. The digital interface operates from a

DIN, CLK, LE, and CLR are +6V tolerant, independent

integrated 35k

Ω bleed resistors on each switch terminal

to discharge capacitive loads.

The devices are drop-in replacements for the Supertex

HV2203 and HV2303. They are available in the 48-pin

LQFP, 26-bump CSBGA, and 28-pin PLCC packages.

All devices are specified for the commercial 0°C to

+70°C temperature range.
