DUAL 4-INPUT MULTIPLEXER The MC74AC153/74ACT153 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 MC74AC153/ 74ACT153 can act as a function generator and generate any two functions of three variables. • Outputs Source/Sink 24 mA • ′ACT153 Has TTL Compatible Inputs VCC 16 Eb 15 S0 14 I3b 13 I2b 12 I1b 11 I0b 10 Zb 9 N SUFFIX CASE 648-08 PLASTIC PIN NAMES 1 2 3 4 5 6 7 8 Ea S1 I3a I2a I1a I0a Za GND I0a–I3a I0b–I3b S0, S1 Ea Eb Za Zb Side A Data Inputs Side B Data Inputs Common Select Inputs Side A Enable Input Side B Enable Input Side A Output Side B Output D SUFFIX CASE 751B-05 PLASTIC TRUTH TABLE Select Inputs Inputs (a or b) Output S0 S1 E I0 I1 I2 I3 Z X L L H X L L L H L L L X L H X X X X L X X X X X X X X L L H L H L L H H L H H H H L L L L L X X X X X H X X X X X L H X X X X X L H H L H L H LOGIC SYMBOL S0 S1 Ea I0a I1a I2a I3a I0b I1b I2b I3b Eb Za H = HIGH Voltage Level L = LOW Voltage Level X = Immaterial FACT DATA 5-1 Zb MC74AC153 MC74ACT153 FUNCTIONAL DESCRIPTION The MC74AC153/74ACT153 is a dual 4-input multiplexer. 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 independently. When the Enables (Ea, Eb) are HIGH, the corresponding outputs (Za, Zb) are forced LOW. The MC74AC153/74ACT153 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 two 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) LOGIC DIAGRAM Ea I0a I1a I2a I3a S1 S0 I0b I2b I1b Za I3b Eb Zb Please note that this diagram is provided only for the understanding of logic operations and should not be used to estimate propagation delays.
