SN54LS51J

Gates And Inverters - Multi-Function, Configurable Overview

The SN54LS51J is a military-grade logic integrated circuit manufactured by Texas Instruments, belonging to the LS (Low-power Schottky) series. It functions as a dual AND-OR-INVERT gate housed in a 16-pin Ceramic Dual In-Line Package (CDIP). The device supports an operating temperature range from -55°C to 125°C and utilizes a glass-sealed ceramic package for environmental durability.
