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
®
technology, this
switch combines high voltage bilateral DMOS switches and
low power CMOS logic to provide efficient control of high volt-
age analog signals.
These ICs are suitable for various combinations of high volt-
age supplies, e.g., V
PP
/V
NN
: +50V/-150V, or +100V/-100V.

Absolute Maximum Ratings are those values beyond which damage to the device
may occur. Functional operation under these conditions is not implied. Continuous
operation of the device at the absolute rating level may affect device reliability. All

The eight switches operate independently.
Serial data is clocked in on the L to H transition of the CLK.
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.
D
OUT
is high when data in the shift register 7 is high.
Shift register clocking has no effect on the switch states if LE is high.
The CLR clear input overrides all other inputs.
