Texas Instruments Signal Switches, Multiplexers, Decoders SN74LV139APWR

The SN74LV139APWR 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 of 7.5 ns at 5 V, making it suitable for high-speed memory decoding and data transmission applications. The device incorporates two enable inputs, facilitating cascading and data reception, and supports mixed-mode voltage operation across all ports. 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 exhibits robust latch-up performance exceeding 250 mA per JESD 17 and provides ESD protection that exceeds standard levels for various models. The SN74LV139APWR is available in a TSSOP package, making it a compact option for space-constrained designs.
