FST16292

12-Bit to 24-Bit Multiplexer/Demultiplexer Bus Switch

General Description

The Fairchild Switch FST16292 provides twelve 2:1 high-

speed CMOS TTL-compatible multiplexer/demultiplexer

bus switches. The low on resistance of the switch allows

inputs to be connected to outputs without adding propaga-

tion delay or generating additional ground bounce noise.

The select pin connects the A Port to the selected B Port

output. The A2 Ports are not externally connected, thus

have a 500Ω pull-down resistor to ground.

Features

s 4Ω switch connection between two ports.

s Minimal propagation delay through the switch.

s Low lCC.

s Zero bounce in flow-through mode.

s Control inputs compatible with TTL level.

s Internal 500Ω pull-down resistor on A2 port.
