QUAD 2-INPUT MULTIPLEXER WITH TRI-STATE OUTPUTS

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 Output Enable (OE) input, allowing the outputs

to interface directly with bus-oriented systems.
