74F257A

Quad 2-line to 1-line selector/multiplexer, non-inverting 3-State

DESCRIPTION The 74F257A has four identical 2-input multiplexers with 3-State outputs which select 4 bits of data from two sources uncer control of a common Select (S) input. The I0a inputs are selected when the common Select input is Low and the I1n inputs are selected when the common Select i
