74F257A - Quad 2-Input Multiplexer

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.

Features

  • s Multiplexer expansion by tying outputs together s Non-inverting 3-STATE outputs s Input clamp diodes limit high-speed termination effects Ordering Code: Order Number 74F257ASC 74F257ASJ 74F257APC Package Number M16A M16D N16E Package.

74F257A Quad 2-Input Multiplexer with 3-STATE Outputs April 1988 Revised August 1999 74F257A 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 with a HIGH on the common Output Enable (OE) input, allowing the outputs to interface directly with bus-oriented systems.
