MC74AC153 MC74ACT153 Dual 4Input Multiplexer The MC74AC153/74ACT153 is a high-speed dual 4-input multiplexer with common select inputs and individual enable inputs for each section. It can select two lines of data from four sources. The two buffered outputs present data in the true (non-inverted) form. In addition to multiplexer operation, the MC74AC153/ 74ACT153 can act as a function generator and generate any two functions of three variables.
