MC74F257A Datasheet (Motorola) - QUAD 2-INPUT MULTIPLEXER

MC74F257A, QUAD 2-INPUT MULTIPLEXER

The F257A is a quad 2-input multiplexer with 3-state outputs.

It selects four bits of data from two sources under control of a Common Data Select input.

When the Select input is LOW, the I0x inputs are selected and when Select is HIGH, the I1x inputs are selected.

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.
