General Description
The Supertex HV2201 is a low charge injection, 8-channel, high
voltage analog switch integrated circuit (IC). The device can be
used in applications requiring high voltage switching controlled by
low voltage control signals, such as medical ultrasound imaging,
piezoelectric transducer drivers, and printers. The HV2201 is an
enhanced version of the HV20220.
Input data is shifted 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.
The device is suitable for various combinations of high voltage
supplies, e.g., VPP/VNN: +40V/-160V, +100V/-100V, and +160V/-
40V.

Notes:
1. The eight switches operate independently.
2. Serial data is clocked in on the L to H transition of the CLK.
3. The switches go to a state retaining their present condition at the rising edge of LE. When LE is low the shift register data flow through the latch.
