Description
SN74LS139N 74139 2V-6V 2-4 Line
Decoder
DIP-16
The SN74LS139N is a dual 2-to-4 line decoder/demultiplexer integrated circuit (IC) designed for high-speed memory decoding and data routing applications. Manufactured by XBLW, this device is optimized for use in digital systems requiring efficient address decoding and signal routing. It features two independent decoders, each accepting two binary inputs and providing four mutually exclusive active-low outputs. The active-low enable (G) inputs allow for cascading and data reception, enhancing the flexibility of system design. The device operates within a voltage range of 2V to 6V, making it suitable for various digital circuits. Its high-speed operation and low propagation delay times contribute to the overall performance of memory systems, minimizing the effects of system decoding. The SN74LS139N is housed in a 16-pin dual in-line package (DIP), facilitating easy integration into existing designs.
Features:
Dual 2-to-4 line decoders/demultiplexers in a single package.
High-speed operation with low propagation delay times.
Active-low enable (G) inputs for cascading and data reception.
Fully buffered inputs to minimize load on driving circuits.
Inputs clamped with high-performance Schottky diodes to suppress line ringing..
