74LS139 LOW POWER SCHOTTKY

The LS139 is a high speed dual 1-of-4 decoder/ demultiplexer fabricated with the Schottky barrier diode process. The device has two independent decoders, each of which accept two binary weighted inputs (A0, A1) and provide four mutually exclusive active LOW outputs (O0 * O3). Each decoder h.

SN74LS139 Dual 1-of-4 Decoder/ Demultiplexer The LSTTL/MSI SN74LS139 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 LS139 can be used as a function generator providing all four minterms of two variables. The LS139 is fabricated with the Schottky .
