8-Bit Bus Switch

General Description

Features

The Fairchild Switch FST3345 provides 8-bits of high-

speed CMOS TTL-compatible bus switching. The low on

resistance of the switch allows inputs to be connected to

outputs without adding propagation delay or generating

additional ground bounce noise.

■ 4Ω switch connection between two ports.

■ Minimal propagation delay through the switch.

■ Low l_CC

■ Zero bounce in flow-through mode.

■ Control inputs compatible with TTL level.

The device is organized as an 8-bit switch bank with dual

output enable inputs (OE and OE). When OE is LOW or

OE is HIGH, the switch is ON and Port A is connected to

Port B. When OE is HIGH and OE is LOW, the switch is

OPEN and a high-impedance state exists between the two

ports.
