74LV257 - Quad 2-input multiplexer

General Description

The 74LV257 is a low-voltage Si-gate CMOS device and is pin and function compatible with 74HC/HCT257.

The 74LV257 is a quad 2-input multiplexer with 3-state outputs, which select 4 bits of data from two sources and are controlled by a common data select input (S).

Key Features

  • Optimized for low voltage.
