74ACT153SJ

Signal Switches, Multiplexers, Decoders Overview

The National Semiconductor 74ACT153SJ is a high-speed silicon-gate CMOS dual 4-input multiplexer. It features common select inputs and individual enable inputs for each section, allowing the selection of two lines of data from four sources. The buffered outputs present data in the true (non-inverted) form. In addition to standard multiplexer operation, this device can function as a logic function generator to produce any two functions of three variables.
