Revised September 2000 74F151A 8-Input Multiplexer General Description The F151A 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 F151A can be used as a universal function generator to generate any logic function of four variables. Both assertion and negation outputs are provided. Ordering Code: Order Number Package Number Package Description 74F151ASC M16A 16-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150 Narrow 74F151ASJ M16D 16-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide 74F151APC N16E 16-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300 Wide Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code. Logic Symbols Connection Diagram IEEE/IEC Unit Loading/Fan Out U.L.

Both assertion and negation outputs are provided. The Enable input (E) is active LOW. When it is not activated, the negation output is HIGH and the assertion output is LOW regardless of all other inputs. The logic function provided at the output is: Inputs Z = E • (I0 S2 S1 S0 + I1 S2 S1 S0 + I2 S2 S1 S0 + I3 S2 S1 S0 + I4 S2 S1 S0 + I5 S2 S1 S0 + Outputs E S2 S1 S0 Z H X X X H L L L L L I0 I0 L L L H I1 I1 L L H L I2 I2 L L H H I3 I3 L H L L I4 I4 L H L H I5 I5 L H H L I6 I6 L H H H I7 I7 Z I6 S2 S1 S0 + I7 S2 S1 S0) The F151A provides the ability, in one package, to select from eight sources of data or control information. By proper manipulation of the inputs, the F151A can provide any logic function of four variables and its negation.
