The 74LS139 is a low-power Schottky TTL IC with two independent 2-to-4 line decoders. Each half has two address inputs, an active-low enable input and four active-low outputs, and can also serve as a 1-to-4 demultiplexer. It is widely used for address decoding in 8-bit computers and microprocessor systems. It runs from a 5 V supply. It comes in a 16-pin plastic DIP.
Condition: mixed surplus lot, untested. The bag may contain used (pulled) ICs of the same type from different manufacturers, so marking and date code vary. The photo shows one chip from this lot (SGS T74LS139B1 98601); only the background was cleaned to white, preserving the marking and leads.
Minimum order: 1 pc.
