The MB74LS139 S is a Dual 2-Line to 4-Line Decoder/Demultiplexer manufactured by FUJ. It is a 16-pin dual in-line package (DIP) integrated circuit (IC).Description: The MB74LS139 S is a dual 2-line to 4-line decoder/demultiplexer. It has two independent 2-line to 4-line decoders/demultiplexers. Each decoder/demultiplexer has two active-low enable inputs (E1 and E2), two active-low data inputs (A and B) and four active-high outputs (Y0 to Y3). When both enable inputs are low, the outputs are active and the selected output is low.Features: Low power Schottky TTL (LSTTL) compatible inputs Outputs can drive up to 10 LSTTL loads Outputs are fully buffered for highest noise immunity Inputs are protected from damage due to static dischargeApplications: The MB74LS139 S is ideal for applications such as memory decoding, address decoding, data routing, and multiplexing. It can be used in computers, communication systems, instrumentation, industrial control, and other digital systems.(For reference only)
