SN74LS169BD TI Synchronous 4-Bit Up/Down Counter | 16-SOIC | 4-Bit, Synchronous

Product Overview

The SN74LS169BD is a synchronous 4-bit up/down binary counter from Texas Instruments, designed for high-performance digital systems. It features a 16-SOIC package and operates with a typical clock frequency of 25 MHz. The counter is fully synchronous, with all flip-flops clocked simultaneously to prevent counting errors. It includes parallel load capability, enabling preset of the counter to any desired value. The up/down control allows bidirectional counting, making it ideal for applications requiring both increment and decrement operations.
