Low-Charge Injection,
8-Channel, High-Voltage Analog Switches
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: VPP/VNN =
+100V/-100V, +185V/-15V, and +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 35kΩ 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°C to +70°C temperature range.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
