General Description
These devices are low charge injection 8-channel high-voltage
analog switch integrated circuits (ICs) intended for use in
applications requiring high voltage switching controlled by low
voltage control signals, such as ultrasound imaging and print-
ers. Input data is shifted into an 8-bit shift register which can
then be retained in an 8-bit latch. To reduce any possible clock
feed-through noise, Latch Enable Bar (LE) should be left high
until all bits are clocked in. Using HVCMOS technology, these
switches combine high voltage bilateral DMOS switches and
low power CMOS logic to provide efficient control of high voltage
analog signals.
These ICs are suitable for various combinations of high voltage
supplies, e.g., VPP/VNN : +50V/–150V, or +100V/–100V.B
