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. Features n n n n ICC reduced by 50% Outputs source/sink 24 mA ’ACT151 has TTL-compatible inputs Standard Microcircuit Drawing (SMD) — ’AC151: 5962-87691 — ’ACT151: 5962-88756 Ordering Code: Logic Symbols IEEE/IEC DS100270-1 DS100270-6 Pin Names I0–I7 S0–S2 E Z Z Description Data Inputs Select Inputs Enable Input Data Output Inverted Data Output FACT ® is a registered trademark of Fairchild Semiconductor Corporation. © 1998 National Semiconductor Corporation DS100270 www.national.com Connection Diagrams Pin Assignment for DIP and Flatpak Pin Assignment for LCC DS100270-2 DS100270-3 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 Z H I0 I1 I2 I3 I4 I5 I6 I7 Outputs Z L I0 I1 I2 I3 I4 I5 I6 I7 Functional Description The ’AC/’ACT151 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...
