Part Number : 74HC258
Function : Quad 2-input multiplexer, 3-state, inverting
Package : DIP 16 Pin type
Maker : NXP Semiconductors.
Pinouts : 
Description :
The 74HC258 is a high-speed Si-gate CMOS device and is pin compatible with low power Schottky TTL (LSTTL). The 74HC258 is specified in compliance with JEDEC standard no. 7A.
The 74HC258 has four identical 2-input multiplexers with 3-state outputs, which select 4 bits of data from two sources and is controlled by a common data select input (S).
