SN74LS697N TI Counter/Register | 20-PDIP | 4-Bit Binary, Synchronous

Product Overview

The SN74LS697N from Texas Instruments is a synchronous 4-bit binary counter with an integrated parallel-load register and a three-state output. Fabricated using low-power Schottky TTL technology, it operates from a single 5V supply and is housed in a 20-pin PDIP package. This device combines counting and storage functions, making it ideal for applications requiring both sequential counting and data retention.
