General Description

The Supertex HV2601 is a low charge injection 16-channel high
voltage analog switch integrated circuit (IC) intended for use in
applications requiring high voltage switching controlled by low
voltage control signals, such as medical ultrasound imaging and
other piezoelectric transducer drivers.

Input data is shifted into a 16-bit shift register that can then be
retained in a 16-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 are 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 effi cient
control of high voltage analog signals.

The device is suitable for various combinations of high voltage
supplies, e.g., V

: +40V/-160V, +100V/-100V, and +160V/-40V.
