General Description
The ACTQ153 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 ACTQ153 can act as a function generator and generate any two functions of three variables.
