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 recom-
mend operation of FACTcircuits outside databook specifications.

General Description
The ’AC/’ACT157 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 ’AC/’ACT157 can also be used as a function generator.

Features
■ ICC and IOZ reduced by 50%
■ Outputs source/sink 24 mA
■ ’ACT157 has TTL-compatible inputs
■ Standard Microcircuit Drawing (SMD)
