General Description
The Supertex HV2221 is a low charge injection, 8-channel,
unipolar, negative high voltage, analog switch integrated
circuit (IC) intended for use in applications requiring high
voltage switching controlled by low voltage control signals,
such as NDT ultrasound flaw detection, medical ultrasound
imaging, piezoelectric transducer drivers, and printers.
Data is input into an 8-bit shift register that can then be
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 efficient control of high voltage analog signals.
