The ’AC/’ACT158 quad 2-input multiplexer selects four bits of data from two sources under the control of a common Se- lect input (S) and presents the data in inverted form at the four outputs. The Enable input (E) is active-LOW. When E is HIGH, all of the outputs (Z) are forced HIGH regardless of all other inputs. The ’AC/’ACT158 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. A common use of the ’AC/’ACT158 is the moving of data from two groups of registers to four common output busses. The particular register from which the data comes is deter- mined by the state of the Select input. A less obvious use is as a function generator. The ’AC/’ACT158 can generate four functions of two variables with one variable common. This is useful for implementing gating functions.
