FST16233

16-Bit to 32-Bit Multiplexer/Demultiplexer Bus Switch

General Description

The Fairchild Switch FST16233 is a 16-bit to 32-bit 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 propaga-

tion delay or generating additional ground bounce noise.

The device can be used in applications where two buses

need to be addressed simultaneously. The FST16233 can

be used as two 8-bit to 16-bit multiplexers or as one 16-bit

to 32-bit multiplexer.

Two select (SEL1, SEL0) and two test (TEST0, TEST1)

inputs provide switch enable and multiplexer select control.

The FST16233 is designed to prevent through-current

when switching buses.

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.
