74LS139 Dual 2-to-4 Line Decoder/Demultiplexer IC
The 74LS139 is an integrated circuit functioning as a dual 2-to-4 line decoder/demultiplexer. It contains two independent decoders. Each decoder converts a 2-bit binary input into one of four active-low outputs. An active-low enable input provides control for demultiplexing operations. Inputs are clamped with Schottky diodes for signal integrity. This IC operates within standard TTL switching voltages. It is suitable for address decoding or data routing applications. The 74LS139 offers performance for digital logic systems.
