74LV257 Overview
The 74LV257 is a low-voltage Si-gate CMOS device and is pin and function patible 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 mon data select input (S). The data inputs from source 0 (1l0 to 4l0) are selected when input S is LOW and the data inputs from source 1 (1l1 to 4l1) are selected when S in HIGH.
