74139 Dual 2-to-4 Line Decoder / Demultiplexer IC – DIP-16

QAR 3.00/ unit

Description

The 74139 is a TTL logic integrated circuit that contains two independent 2-to-4 line decoders/demultiplexers in a single package. Each decoder accepts 2 binary input lines and activates one of four active-low outputs based on the input combination. With independent enable inputs , each decoder section can be controlled separately, making the 74139 ideal for address decoding, memory selection, signal routing, and digital control applications. Operating on a standard 5V TTL supply , it is widely used in embedded systems, microprocessor interfaces, and digital electronics projects.
