MC74AC139, MC74ACT139 Dual 1−of−4 Decoder/Demultiplexer The MC74AC139/74ACT139 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 MC74AC139/74ACT139 can be used as a function generator providing four minterms of two variables. • • • • • w Multifunctional Capability Two Completely Independent 1−of−4 Decoders Active LOW Mutually Exclusive Outputs Outputs Source/Sink 24 mA ′ACT139 Has TTL Compatible Inputs Eb A0b A1b O0b O1b O2b O3b 16 15 14 13 12 11 10 9 DIP−16 N SUFFIX CASE 648 16 1 These devices are available in Pb−free package(s).

Figure 3. Logic Diagram FUNCTIONAL DESCRIPTION E E A0 The MC74AC139/74ACT139 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 enable can be used as the data input for a 4−output demultiplexer application. Each half of the MC74AC139/74ACT139 generates all four minterms of two variables. These four minterms are useful in some applications, replacing multiple gate functions as shown in Figure 4, and thereby reducing the number of packages required in a logic network.
