Product Overview
The SNJ54LS592J is a high-performance 8-bit binary counter with an input storage register and 3-state output buffers from Texas Instruments. It integrates counting, storage, and output control in a single monolithic IC, designed for military and aerospace applications requiring extended temperature range and high reliability. The device features an 8-bit binary counter that can be loaded synchronously, an 8-bit storage register that captures counter data on a separate clock, and 3-state outputs that allow connection to a common bus. Operating from a single 5V supply, it offers typical count frequencies up to 35 MHz and low power consumption of 45 mW. The SNJ54LS592J is available in a 16-pin ceramic DIP package (J suffix) and is fully specified over the -55°C to +125°C temperature range.
