54F/74F139 Dual 1-of-4 Decoder/Demultiplexer General Description Features The ’F139 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 ’F139 can be used as a function generator providing all four minterms of two variables.

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 enable can be used as the data input for a 4-output demultiplexer application. Each half of the ’F139 generates all four minterms of two variables. These four minterms are useful in some applications, replacing multiple gate functions as shown in Figure 1 , and thereby reducing the number of packages required in a logic network.
