FST3245 — 8-Bit Bus Switch

Features

CC

Description

The FST3245 switch provides eight-bits of high-speed

CMOS TTL-compatible bus switching in a standard ’245

pin-out. The low on resistance allows inputs to be

connected to outputs without adding propagation delay

or generating additional ground bounce noise.

The device is organized as an eight-bit switch. 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.
