MC74F151

MC54/74F151 8-INPUT MULTIPLEXER The MC54/74F151 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 F151 can be used as a universal function generator to generate any logic function of four variables. Both asserted and negated outputs are provided. The F151 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. The Enable input (E) is active LOW. 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) CONNECTION DIAGRAM DIP (TOP VIEW) VCC 16 I4 15 I5 14 I6 13 I7 12 S0 11 S1 10 S2 9 16 1 8-INPUT MULTIPLEXER FAST™ SHOTTKY TTL J SUFFIX CERAMIC CASE 620-09 16 1 N SUFFIX PLASTIC CASE 648-08 1 I3 2 I2 3 I1 4 I0 5 Z 6 Z 7 E 8 GND D SUFFIX SOIC CASE 751B-03 LOGIC DIAGRAM I0 S2 S1 S0 E I1 I2 I3 I4 I5 I6 I7 16 1 ORDERING INFORMATION MC54FXXXJ MC74FXXXN MC74FXXXD Ceramic Plastic SOIC LOGIC SYMBOL Z Z 12 13 14 15 1 2 3 4 7 I7 I6 I5 Z I4 I3 I2 I1 Z I0 ES S S 0 1 2 11 10 9 VCC = PIN 16 GND = PIN 8 FUNCTION 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 Z H I0 I1 I2 I3 I4 I5 I6 I7 Outputs Z L I0 I1 I2 I3 I4 I5 I6 I7 5 6 H = HIGH Voltage Level; L = LOW Voltage Level; X = Don’t Care FAST AN...
