MV54ACT257-X REV 0A0
Quad 2-Input Multiplexer With TRI-State Outputs
General Description
The ACT257 is a quad 2-input multiplexer 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 (noninverted) form. The outputs may be switched to a high impedance
state by placing a logic HIGH on the common Output Enable (OE) input, allowing the outputs
to interface directly with bus-oriented systems.

Note 1: Absolute maximum ratings are those values beyond which damage to the device may
occur. The databook specifications should be met, without exception, to ensure that
the system design is reliable over its power supply, temperature, and output/input
loading variables. National does not recommend operation of FACT TM circuits outside
databook specifications.
