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.
