General Description
The Supertex HV230 and HV232 are low charge injection
8-channel high-voltage analog switch integrated circuits
(ICs) with bleed resistors. These devices can be used in
applications requiring high voltage switching controlled by
low voltage control signals, such as ultrasound imaging
and printers. The bleed resistors eliminate voltage built up
on capacitive loads such as piezoelectric transducers.
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 voltage analog signals.
These ICs are suitable for various combinations of high
voltage supplies, e.g., V

: +50V/150V, or
+100V/100V.

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