FST3257
Quad 2:1 Multiplexer / Demultiplexer Bus Switch
Features
4
Ω Switch Connection Between Two Ports
Minimal Propagation Delay Through the Switch
Low ICC
Zero Bounce in Flow-Through Node
Control Inputs Compatible with TTL Level
Description
The Fairchild Switch FST3257 is a quad 2:1 high-speed
CMOS TTL-compatible multiplexer / demultiplexer bus
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.
