General Description
The Supertex HV230 and HV232 are low charge injection
8-channel high-voltage analog switch integrated circuits
(ICs) with bleed resistors. These devices 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 transducers.
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.
These ICs are suitable for various combinations of high
voltage supplies, e.g., V

+100V/–100V.
