SN74LS591D TI 8-Bit Binary Counter | 8-Bit, 3-State Output

Product Overview

The SN74LS591D is a monolithic 8-bit binary counter with output latches and 3-state outputs from Texas Instruments. It integrates counting, latching, and bus-driving capabilities in a single IC, making it ideal for microprocessor interface applications. The device features an asynchronous clear, a synchronous count enable, and a ripple-carry output for cascading multiple counters. The 3-state outputs allow direct connection to a common bus, and the output latches hold the count value during counting operations.
