SN74LS257B SN74LS258B

Quad 2-Input Multiplexer

with 3-State Outputs

The LSTTL / MSI SN74LS257B and the SN74LS258B 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 (E

) 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 ON Semiconductor TTL families.
