MICROCIRCUIT DATA SHEET Original Creation Date: 07/02/96 Last Update Date: 03/17/97 Last Major Revision Date: 07/02/96 MN54ACT257-X REV 1B0 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.

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.
