The is a high-speed, dual 1-of-4 decoder/ demultiplexer. The device has two independent decoders, each accepting two inputs and providing four mutually-exclusive active-LOW outputs. Each decoder has an active-LOW Enable input which can be used as a data input for a 4-output demultiplexer. Each half of the 'AC/ 'ACT139 can be used as a function generator providing all four minterms of two variables. Multifunction capability Two completely independent 1-of-4 decoders Active LOW mutually exclusive outputs Outputs source/sink mA 'ACT139 has TTL-compatible inputs Standard Military Drawing (SMD) 'ACT139: 5962-87553Features
Description Address Inputs Enable Inputs Outputs
FACT is a registered trademark of Fairchild Semiconductor Corporation.
Pin Assignment for DIP and Flatpak can be used as the data input for a 4-output demultiplexer application. Each half of the 'AC/'ACT139 generates all four minterms of two variables. These four minterms are useful in some applications, replacing multiple gate functions as shown in , and thereby reducing the number of packages required in a logic network.
The is a high-speed dual 1-of-4 decoder/ demultiplexer. The device has two independent decoders, each of which accepts two binary weighted inputs (A0�A1) and provides four mutually exclusive active-LOW outputs (O0�O3). Each decoder has an active-LOW enable (E). When E is HIGH all outputs are forced HIGH. The enableH = HIGH Voltage Level L = LOW Voltage Level X = Immaterial
