74S139AN - Brand New Texas Instruments Signal Switches / Encoders & Decoders / Multiplexers
-
Description
Electonic Component Model: 74S139AN is a Schottky-clamped circuit designed for high-performance memory-decoding or data-routing applications with very short propagation delay times. It is commonly used in high-speed memory systems to minimize the effects of system decoding and reduce the overall access time of the memory. With its negligible system delay, it offers optimal performance for various electronic applications.
Specifications and features
- Designed specifically for high speed applications such as memory decoders and data transmission systems
- DM74S138 3-to-8-line decoders incorporate 3 enable inputs to simplify cascading and/or data reception
- DM74S139 contains two fully independent 2-to-4-line decoders/demultiplexers
- Schottky clamped for high performance
- Typical propagation delay time (3 levels of logic): DM74S138 - 8 ns, DM74S139 - 7.5 ns
- Typical power dissipation: DM74S138 - 245 mW, DM74S139 - 300 mW
