Note 1: Absolute maximum ratings are those values beyond which damage to the device may
occur. The databook specification 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.


Description

The MN54AC258-X 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 the complement (inverted) form. The outputs of MN54AC258-X may be switched to a high impedance state with a logic HIGH on the common Output Enable (OE) input, allowing the outputs to interface directly with bus-oriented systems.
