Overview
74AHC257; 74AHCT257 Quad 2-input multiplexer; 3-state Rev.
02 — 9 May 2008 Product data sheet 1.
General description The 74AHC257; 74AHCT257 is a high-speed Si-gate CMOS device and is pin compatible with Low-power Schottky TTL (LSTTL).
It is specified in compliance with JEDEC standard No.
7-A.
The 74AHC257; 74AHCT257 has four identical 2-input multiplexers with 3-state outputs, which select 4 bits of data from two sources and are controlled by a common data select input (S).
The data inputs from source 0 (1I0 to 4I0) are selected when input S is LOW and the data inputs from source 1 (1I1 to 4I1) are selected when input S is HIGH.
Data appears at the outputs (1Y to 4Y) in true (non-invertin...
