General Description

The Supertex HV232 is a low charge injection 8-channel high-

voltage analog switch integrated circuit (IC) with bleed resistors.

The device can be used in applications requiring high voltage

switching controlled by low voltage control signals, such as

ultrasound imaging and printers. The bleed resistors eliminate

voltage built up on capacitive loads such as piezoelectric trans-

ducers. Input data is shifted into an 8-bit shift register which can

then be retained in an 8-bit latch. To reduce any possible clock

feed-through noise, Latch Enable Bar (LE) should be left high

until all bits are clocked in. Using HVCMOS technology, this

switch combines high voltage bilateral DMOS switches and low

power CMOS logic to provide efficient control of high voltage

analog signals.

This IC is suitable for various combinations of high voltage

supplies, e.g., V /V : +50V/–150V, or +100V/–100V.
