54AC158 · 54ACT158 Quad 2-Input Multiplexer
General Description
The 'AC/'ACT158 is a high-speed quad 2-input multiplexer. It selects four bits of data from two sources using the common Select and Enable inputs. The four buffered outputs present the selected data in the inverted form. The 'AC/'ACT158 can also be used as a function generator. n Outputs source/sink 24 mA n 'ACT158 has TTL-compatible inputs n Standard Microcircuit Drawing (SMD) -- 'AC158: 5962-89729 -- 'ACT158: 5962-88755

Functional Description
The 'AC/'ACT158 quad 2-input multiplexer selects four bits of data from two sources under the control of a common Select 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 determined 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.

Note 1: Absolute maximum ratings are those values beyond which damage to the device may occur. The databook specifications should be met, without exception, to ensure that the system design is reliable over its power supply, temperature, and output/input loading variables. National does not recommend operation of FACTTM circuits outside databook specifications.
