54AC153 * 54ACT153 Dual 4-Input Multiplexer General Description Features The 'AC/'ACT153 is a high-speed dual 4-input multiplexer with common select inputs and individual enable inputs for each section. 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. n n n n ICC reduced by 50% Outputs source/sink 24 mA 'ACT153 has TTL-compatible inputs Standard Microcircuit Drawings (SMD) -- 'AC153: 5962-87625 -- 'ACT153: 5962-87698 Logic Symbols IEEE/IEC DS100271-1 DS100271-2 Pin Names Description I0a-I3a Side A Data Inputs I0b-I3b Side B Data Inputs S0, S1 Common Select Inputs Ea Side A Enable Input Eb Side B Enable Input Za Side A Output Zb Side B Output FACT (R) is a registered trademark of Fairchild Semiconductor Corporation.

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 + Select Inputs (a or b) I2a * S1 * S0 + I3a * S1 * S0) Zb = Eb * (I0b * S1 * S0 + I1b * S1 * S0 + I2b * S1 * S0 + I3b * S1 * S0) S0 S1 E I0 I1 I2 I3 Z X X H X X X X L L L L L X X X L L L L H X X X H H L L X L X X L H L L X H X X H L H L X X L X L L H L X X H X H H H L X X X L L H H L X X X H H H = HIGH Voltage Level L = LOW Voltage Level X = Immaterial www.national.com Output Inputs 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) Recommended Operating Conditions If Military/Aerospace specified devices are required, please contact the National Semiconductor Sales Office/ Distributors for availability and specifications.
