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™ circuits outside databook specifications.

The 54ACT157 is a high-speed quad 2-input multiplexer. Four bits of data from two sources can be selected using the common Select and Enable inputs. The four outputs present the selected data in the true (noninverted) form. The 54ACT157 can also be used as a function generator.
