General Description
This device is a low charge injection, 8-channel, high-voltage
analog switch integrated circuit (IC) intended for use in appli-
cations requiring high voltage switching controlled by low volt-
age control signals, such as ultrasound imaging and printers.
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
switch combines high voltage bilateral DMOS switches and
low power CMOS logic to provide effi cient control of high volt-
age analog signals.
These ICs are suitable for various combinations of high volt-
age supplies, e.g., V
