DUAL 2-LINE TO 4-LINE DECODERS/DEMULTIPLEXERS
The SN74S139AN is a 16-pin dual 2-line to 4-line decoder/demultiplexer manufactured by Texas Instruments. It is part of the 74S series of logic ICs. Description: The SN74S139AN is a dual 2-line to 4-line decoder/demultiplexer. It has two active-low enable inputs (E1 and E2), two active-low data inputs (A and B), and four active-low outputs (Y0Y3). When both enable inputs are low, the outputs are active. When either enable input is high, all outputs are low. Features: Low power consumption High noise immunity High speed operation TTL compatible 16-pin DIP package Applications: The SN74S139AN is commonly used in applications such as address decoding, data routing, and multiplexing/demultiplexing. It can also be used in logic circuits such as counters, decoders, and multiplexers. (For reference only)
