CD74HC22106

QMOS 8 x 8 x 1 Crosspoint Switches with

Memory Control

The CD74HC22106 is a digitally controlled analog switch

which utilize silicon-gate CMOS technology. The

CD74HC22106 features CMOS input-voltage-level

compatibility.

The Master Reset has an internal pull-up resistor and is

normally used with a 0.1

µF capacitor. During power up all

switches are automatically reset. The crosspoint switches

will reset with MR = 0 even if CE is high. A 6-bit address

through a 6 line to 64 line decoder selects the transmission

gate which can be turned on by applying a logic ONE to the

DATA input and logic ZERO to the STROBE. Similarly, any

transmission gate can be turned OFF by applying a logic

ZERO to the DATA input while strobing the STROBE with a

logic ZERO.

The CE pin allows the crosspoint array to be cascaded for

matrix expansion in both the X and Y directions.

Features

• 64 Analog Switches in an 8 x 8 x 1 Array

• On-Chip Line Decoder and Control Latches

• Automatic Power-Up Reset by Using a 0.1

µF Capacitor at

the MR Pin

• 2V to 10V Operation
