It can select two lines of data from four sources. The two buffered outputs present data in the true (non-inverted) form. In addition to multiplexer operation, the ’AC/’ACT153 can act as a function generator and generate any two functions of three variables.

It can select two bits of data from up to four sources under the control of the common Select inputs (S0, S1). The two 4-input multiplexer circuits have individual active-LOW Enables (Ea, Eb) which can be used to strobe the outputs indepedently. When the Enables (Ea, Eb) are HIGH, the corresponding outputs Za, Zb) are forced LOW. The ’AC/’ACT153 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 Select inputs. The logic equations for the outputs are shown below. Za = Ea • (I0a • S1 • S0 + I1a • S1 • S0 + I2a • S1 • S0 + I3a • S1 • S0) Zb = Eb • (I0b • S1 • S0 + I1b • S1 • S0 + I2b • S1 • S0 + I3b • S1 • S0) Truth Table Select Inputs S0 X L L H H L L H H S1 X L L L L H H H H E H L L L L L L L L I0 X L H X X X X X X I1 X X X L H X X X X I2 X X X X X L H X X I3 X X X X X X X L H Z L L H L H L H L H Inputs (a or b) Output H = HIGH Voltage Level L = LOW Voltage Level X = Immaterial www.national.com 2 Logic Diagram DS100271-5 Please note that this diagram is provided only for the understanding of logic operations and should not be used to estimate propagation delays. 3 www.national.com Absolute Maximum Ratings (Note 1) If Military/Aerospace specified devices are required, please contact the National Semiconductor Sales Office/ Distributors for availability and specifications.
