74AHCT157 Overview
The 74AHC/AHCT157 are high-speed Si-gate CMOS devices and are pin patible with Low Power Schottky TTL (LSTTL). They are specified in pliance with JEDEC standard no. The 74AHC/AHCT157 are quad 2-input multiplexer which select 4 bits of data from two sources under the control of a mon data select input (S).
