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.

Notes:
1. The eight switches operate independently.
2. Serial data is clocked in on the L to H transition of the CLK.
3.
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.
4. D
OUT
is high when data in the shift register 7 is high.
5. Shift register clocking has no effect on the switch states if LE is high.
6. The CLR clear input overrides all other inputs.
