FST3244 — 8-Bit Bus Switch

Features

Description

The FST3244 switch provides eight-bits of high-speed,

CMOS, TTL-compatible bus switching in a standard

’244 pin-out. The low on resistance 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 I_CC

Zero Bounce in Flow-through Mode

Control Inputs Compatible with TTL Level

The device is organized as two four-bit switches with

separate /OE inputs. When /OE is LOW, the switch is

ON and port A is connected to port B. When /OE is

HIGH, the switch is OPEN and a high-impedance state

exists between the two ports.
