Features

Description

The CPC7220 is a low charge injection 8-channel

high-voltage analog switch integrated circuit (IC) for

use in applications requiring high voltage switching.

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 CPC7220 is capable of switching high

load voltages and has a flexible load voltage range,

e.g. V

suited for many medical and industrial applications

such as medical ultrasound imaging, printers, and

industrial measurement equipment.

Construction of the high voltage switches using

Clare's reliable BCDMOS process technology on

SOI (Silicon On Insulator) allow the switches to be

organized as solid state switches with direct gate

drive.
