General Description
The Supertex HV2321 is a low charge injection, 8-channel,
unipolar, negative 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 signals,
such as NDT metal 鏗俛w detection, medical ultrasound imaging,
piezoelectric transducer drivers, and printers. The bleed resistors
eliminate voltage built up on capacitive loads such as piezoelectric
transducers.
Data is input into an 8-bit shift register and then retained in an 8-bit
latch. To reduce any possible clock feed-through noise, the latch
enable bar should be left high until all bits are clocked in. Data is
clocked in during the rising edge of the clock.
Using HVCMOS technology, this device combines high voltage
bilateral DMOS switches and low power CMOS logic to provide
ef鏗乧ient control of high voltage analog signals.
