74AC151 • 74ACT151 8-Input Multiplexer 74AC151 • 74ACT151 8-Input Multiplexer The AC/ACT151 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 AC/ACT151 can be used as a universal function generator to generate any logic function of four variables. Both true and complementary outputs are provided. s ICC reduced by 50% s Outputs source/sink 24 mA s ACT151 has TTL-compatible inputs Ordering Code: Order Number Package Number Package Description 74AC151SC M16A 16-Lead Small Outline Integrated Circuit SOIC , JEDEC MS-012, Narrow Body 74AC151SJ M16D 16-Lead Small Outline Package SOP , EIAJ TYPE II, 5.3mm Wide 74AC151MTC MTC16 16-Lead Thin Shrink Small Outline Package TSSOP , JEDEC MO-153, 4.4mm Wide 74AC151PC N16E 16-Lead Plastic Dual-In-Line Package PDIP , JEDEC MS-001, Wide 74ACT151SC M16A 16-Lead Small Outline Integrated Circuit SOIC , JEDEC MS-012, Narrow Body 74ACT151SJ M16D 16-Lead Small Outline Package SOP , EIAJ TYPE II, 5.3mm Wide 74ACT151PC N16E 16-Lead Plastic Dual-In-Line Package PDIP , JEDEC MS-001, Wide Device also available in Tape and Reel.

Both true and com- plementary 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 + I 7 • S0 • S1 • S2 The AC/ACT151 provides the ability, in one package, to select from eight sources of data or control information. By proper manipulation of the inputs, the AC/ACT151 can pro- vide any logic function of four variables and its complement.
