General Description
The Supertex HV2605 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 are 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 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.
