HD74AC157 Quad 2-Input Multiplexer REJ03D0252-0200Z (Previous ADE-205-371 (Z)) Rev.2.00 Jul.16.2004 Description The HD74AC157 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 HD74AC157 can also be used as a function generator.

It selects four bits of data from two sources under the control of a common Select input (S). The Enable input (E) is active-Low. when E is High, all of the outputs (Z) are forced Low regardless of all other inputs. The HD74AC157 is the logic implementation of a 4-pole, 2-position switch where the position of the switch is determined by the logic levels supplied to the Select input. The logic equations for the outputs are shown below: Za = E*(I1a*S + I0a*S) Zb = E*(I1b*S + I0b*S) Zc = E*(I1c*S + I0c*S) Zd = E*(I1d*S + I0d*S) A common use of the HD74AC157 is the moving of data from two groups of register to four common output busses. The particular register from which the data comes is determined by the state of the Select input. A less obvious use is as a function generator. The HD74AC157 can generate any four of the sixteen different functions of two variables with one variable common. This is useful for implementing gating functions.
