FSAL200

Wide Bandwidth Quad 2:1 Analog

Multiplexer/Demultiplexer Switch

General Description

The Fairchild Switch FSAL200 is a rail-to-rail quad 2:1

high-speed CMOS TTL-compatible analog multiplexer/

demultiplexer switch. The low On Resistance of the switch

allows inputs to be connected to outputs without adding

propagation delay or generating additional ground bounce

noise.

When OE is LOW, the select pin connects the A Port to the

selected B Port output. When OE is HIGH, the switch is

OPEN and a high-impedance state exists between the two

ports.
