Texas Instruments Signal Switches, Multiplexers, Decoders SN74LV139ADGVRG4

The SN74LV139ADGVRG4 is a dual 2-line to 4-line decoder/demultiplexer designed for operation within a voltage range of 2 V to 5.5 V. It features a maximum propagation delay time of 7.5 ns at 5 V, making it suitable for high-speed memory decoding and data transmission applications. The device supports mixed-mode voltage operation on all ports and includes two enable inputs to facilitate cascading and data reception. This decoder is fully buffered, ensuring minimal load on the driving circuit, and is specified for partial-power-down applications, utilizing Ioff to disable outputs and prevent backflow current when powered down. The device also offers robust ESD protection, exceeding standards for human-body, machine, and charged-device models. The operating temperature range is from -40¬8C to 85¬8C, making it versatile for various environments. Engineers considering this product should note its suitability for high-performance applications requiring low propagation delays and its ability to simplify circuit design through its enable features.
