Quad 2-Input Multiplexer with 3-STATE Outputs

General Description The 74F257A is a quad 2-input multiplexer with 3-STATE outputs. Four bits of data from two sources can be selected using a Common Data Select input. The four outputs present the selected data in true (non-inverted) form. The outputs may be switched to a high impedance state wi

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
