Signal Switches, Multiplexers, Decoders datasheet and documents for SNJ54LS155AJ
Signal Switches, Multiplexers, Decoders Overview
The SNJ54LS155AJ is a military-grade dual 2-line to 4-line decoder/demultiplexer manufactured by Texas Instruments. It operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature range from -55°C to 125°C. The device features a maximum propagation delay of 27ns at nominal voltage, with a maximum input leakage current of 5µA. It provides two independent channels, each decoding two address bits to select one of four outputs. The component utilizes a 16-pin ceramic dual in-line package (CDIP) designed for high reliability in demanding environments.
