Texas Instruments has been making progress possible for decades. TI is a global semiconductor company that designs, manufactures, tests, and sells analog and embedded processing chips. The company's approximately 80,000 products help more than 100,000 customers efficiently manage power, accurately sense and transmit data, and provide the core control or processing in their designs, going into markets such as industrial, automotive, personal electronics, communications equipment, and enterprise systems. TI's passion to create a better world by making electronics more affordable through semiconductors is alive today as each generation of innovation builds upon the last to make our technology smaller, more efficient, more reliable, and more affordable – opening new markets and making it possible for semiconductors to go into electronics everywhere. TI thinks of this as Engineering Progress. It’s what TI does and has been doing for decades.

 

Texas Instruments SN74AHC139/SN74AHC139-Q1 2-to-4 Line Decoder/Demux

Texas Instruments SN74AHC139/SN74AHC139-Q1 Dual 2-to-4 Line Decoder / Demultiplexers are designed for data-routing and high-performance memory-decoding applications requiring short propagation-delay times. These decoders can be used to minimize the effects of system decoding in high-performance memory systems. The delay times of these decoders and the enable time of the memory are usually less than the typical access time when employed with high-speed memories utilizing a fast enable circuit. This feature means that the effective system delay introduced by the decoders is negligible. The Texas Instruments SN74AHC139-Q1 devices are AEC-Q100 qualified for automotive applications.

FEATURES

  • Operating range 2V to 5.5V VCC
  • Designed specifically for high-speed memory decoders and data-transmission systems
  • Incorporate two enable inputs to simplify cascading and/or data reception
  • Latch-up performance exceeds 250mA per JESD 17
  • ESD protection exceeds JESD 22
    • 2000V Human-Body Model (A114-A)
    • 1000V Charged-Device Model (C101)

APPLICATIONS

  • Memory device selection with shared data bus
  • Route data
  • Reduce the required number of outputs for chip-select applications
