General Description
Not recommended for new designs. Please use HV20220 for
new designs.
This device is a low charge injection 8-channel high-voltage ana-
log switch integrated circuit (IC) intended for use in applications
requiring high voltage switching controlled by low voltage 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 feedthrough 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 voltage analog signals.

Notes:
1. The eight switches operate
independently.
2. Serial data is clocked in on
the L→ H transition 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 flows through
the latch.
4. DOUT is high when switch 7 is
on.
5. Shift register clocking has no
effect on the switch states if
LE is H.
