NC7SZ157

TinyLogic

 UHS 2-Input Non-Inverting Multiplexer

General Description

The NC7SZ157 is a single, high performance, 2 to 1

CMOS non-inverting multiplexer from Fairchild’s Ultra High

Speed Series of TinyLogic

. The device is fabricated with

advanced CMOS technology to achieve ultra high speed

with high output drive while maintaining low static power

ing range. The inputs and outputs are high impedance
