SN54LS257B - QUAD 2-INPUT MULTIPLEXER

General Description

The LS257B and LS258B are Quad 2-Input Multiplexers with 3-state outputs.

They select four bits of data from two sources each under control of a Common Data Select Input.

When the Select Input is LOW, the I0 inputs are selected and when Select is HIGH, the I1 inputs are selected.

QUAD 2-INPUT MULTIPLEXER WITH 3-STATE OUTPUTS The LSTTL / MSI SN54 / 74LS257B and the SN54 / 74LS258B are Quad 2-Input Multiplexers 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 (EO) Input, allowing the outputs to interface directly with bus oriented systems. It is fabricated with the Schottky barrier diode process for high speed and is completely compatible with all Motorola TTL families.
