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 (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 ON Semiconductor TTL families.
