Hitachi HD74AC153
The HD74AC153 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 (noninverted) form.| Part No. | HD74AC153 |

DESCRIPTION
The HD74AC153 is a dual 4-input multiplexer. It can select two bits of data from up to four sources under the control of the common Select inputs (S 0, S1). The two 4-input multiplexer circuits have individual active-Low Enables (Ea , Eb) which can be used to strobe the outputs independently. When the Enables ( Ea , Eb ) are High, the corresponding outputs (Za , Zb ) are forced Low. The HD74AC153 is the logic implementation of a 2-pole, 4-position switch, where the position of the switch is determined by the logic levels supplied to the two Select inputs.
