2:1 Multiplexer/Demultiplexer Bus Switch

General Description

The NC7SB3257 is a high performance, 2:1 NMOS pass-

gate multiplexer/demultiplexer from Fairchild’s Ultra High

Speed Series of TinyLogic

. The device is fabricated with

advanced sub-micron CMOS technology to achieve high

speed enable and disable times and low On Resistance.

The device is specified to operate over the 4.0 to 5.5V V

operating range. The control input tolerates voltages up to

5.5V independent of the V

operating range.

Features
