Description

The CPC7232 is a low charge injection 8-channel

high-voltage analog switch integrated circuit (IC) for

use in applications requiring high voltage switching.

Bleeder resistors are incorporated into both terminals

of each output switch. Control of the high voltage

switching is via low voltage TTL logic level compatible

inputs for direct connectivity to the system controller.

Switch manipulation is managed by an 8-bit serial to

parallel shift register whose outputs are buffered and

stored by an 8-bit transparent latch. Level shifters

buffer the latch outputs and operate the high voltage

switches.

Because the CPC7232 is capable of switching high

load voltages and has a flexible load voltage range,

e.g. VPP/VNN: +40V/160V or +100V/100V, it is well

suited for many medical and industrial applications

such as medical ultrasound imaging, printers, and

industrial measurement equipment. The bleeder

resistors enable the discharge of capacitive loads,

such as piezoelectric transducers, connected to the

output switches of the CPC7232.

Construction of the high voltage switches using IXYS

Integrated Circuits Division's reliable BCDMOS

process technology on SOI (Silicon On Insulator)

allow the switches to be organized as solid state

switches with direct gate drive.
