74F257A - Quad 2-Input Multiplexer

Download the 74F257A datasheet PDF. This datasheet also covers the 74F257APC variant, as both devices belong to the same quad 2-input multiplexer family and are provided as variant models within a single manufacturer datasheet.

General Description

The ’F257A is a quad 2-input multiplexer with TRI-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 with a HIGH on the common O
