Low Charge Injection 8-Channel High Voltage

Analog Switches with Bleed Resistors

Features

General Description

The Supertex HV230 and HV232 are low charge injection

❏

HVCMOS^®technology for high performance

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

clockfeed-throughnoise, LatchEnableBar(LE)shouldbe

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.

Very low quiescent power dissipation – 10µA

Output On-resistance typically 22 ohms

Integrated bleed resistors on the outputs

Low parasitic capacitances

DC to 10MHz analog signal frequency

-60dB typical output off isolation at 5MHz

CMOS logic circuitry for low power

Excellent noise immunity

On-chip shift register, latch and clear logic circuitry

Flexible high voltage supplies

Applications

These ICs are suitable for various combinations of high

voltage supplies, e.g., V_PP/V_NN: +50V/–150V, or

+100V/–100V.
