| MC74AC151 MC74ACT151 1 of 8 Decoder/Demultiplexer The MC74AC151/74ACT151 is a high-speed 8-input digital multiplexer. It provides, in one package, the ability to select one line of data from up to eight sources. The MC74AC151/74ACT151 can be used as a universal function generator to generate any logic function of four variables. Both true and complementary outputs are provided. * Outputs Source/Sink 24 mA * ACT151 Has TTL Compatible Inputs 1-OF-8 DECODER/DEMULTIPLEXER VCC 16 I4 15 I5 14 I6 13 I7 12 S0 11 S1 10 S2 9 N SUFFIX CASE 648-08 PLASTIC PIN NAMES I0-I7 S0-S2 E Z Z Data Inputs Select Inputs Enable Input Data Output Inverted Data Output 1 I3 2 I2 3 I1 4 I0 5 Z 6 Z 7 E 8 GND D SUFFIX CASE 751B-05 PLASTIC TRUTH TABLE Inputs E H L L L L L L L L S2 X L L L L H H H H S1 X L L H H L L H H S0 X L H L H L H L H Outputs Z H I0 I1 I2 I3 I4 I5 I6 I7 Z L I0 I1 I2 I3 I4 I5 I6 I7 LOGIC SYMBOL S0 E I0 I1 I2 I3 I4 I5 I6 I7 S1 S2 Z Z H = HIGH Voltage Level L = LOW Voltage Level X = Immaterial FACT DATA 5-1 MC74AC151 MC74ACT151 FUNCTIONAL DESCRIPTION The MC74AC151/74ACT151 is a logic implementation of a single pole, 8-position switch with the switch position controlled by the state of three Select inputs, S0, S1, S2. Both true and complementary outputs are provided. The Enable input (E) is active LOW. When it is not activated, the complementary output is HIGH and the true output is LOW regardless of all other inputs. The logic function provided at the output is: Z = E*(I0*S0*S1*S2+I1*S0*S1*S2+ I2*S0*S1*S2+I3*S0*S1*S2+ I4*S0*S1*S2+I5*S0*S1*S2+ I6*S0*S1*S2+I7*S0*S1*S2) The MC74AC151/74ACT151 provides the ability, in one package, to select from eight sources of data or control information. By proper manipulation of the inputs, the MC74AC151/74ACT151 can provide any logic function of four variables and its complement.
