SNJ54LVC138AJ

Signal Switches, Multiplexers, Decoders Overview

The SNJ54LVC138AJ is a military-grade 3-to-8 line decoder and demultiplexer manufactured by Texas Instruments. It operates from a supply voltage of 2 V to 3.6 V with inputs accepting voltages up to 5.5 V. The device features inverted outputs and includes three enable inputs (one active-high, two active-low). It provides a maximum propagation delay of 6.7 ns at 3.3 V and exhibits latch-up performance exceeding 250 mA per JESD 17 standards.
