SNJ54LS156J TI Logic Decoder | Dual 2-to-4 Line | Military Temp, 4.5V-5.5V

Product Overview

The SNJ54LS156J is a high-performance dual 2-to-4 line decoder/demultiplexer from Texas Instruments, designed for military and aerospace applications. It features two independent decoders with active-low outputs, each capable of decoding a 2-bit binary input into one of four mutually exclusive outputs. The device operates over the full military temperature range (-55°C to +125°C) and is packaged in a hermetic ceramic DIP (J package). It is fabricated using advanced low-power Schottky (LS) technology, providing a balance of speed and power consumption.
