74act158 quad 2-input multiplexer ?988 fairchild semiconductor corporation www.fairchildsemi.com 74act158 rev. 1.4 2 functional description the 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 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 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 obvi- ous use is as a function generator. the act158 can generate four functions of two variables with one vari- able common. this is useful for implementing gating functions. truth table h = high voltage level l = low voltage level x = immaterial logic diagram please note that this diagram is provided only for the understanding of logic operations and should not be used to estimate propagation delays. figure 1. inputs outputs e si 0 i 1 z hx x x h ll l x h ll h x l lh x l h lh x h l
