IC 74161 4-Bit Synchronous Binary Counter
- High-speed 4-bit synchronous binary counter with parallel load
- Includes asynchronous clear for quick reset functionality
- TTL-compatible for stable and reliable operation
- Ideal for timing, sequencing, and digital counting applications
- Can be cascaded for extended counting beyond 4 bits
- Compact 16-pin DIP package for easy prototyping and integration
Description
The IC 74161 4-Bit Synchronous Binary Counter is a high-speed, fully TTL-compatible counter designed for use in digital counting, timing, and sequencing circuits. It features synchronous operation, meaning all flip-flops are clocked simultaneously, ensuring precise and stable counting performance. The device includes a parallel load function for presetting data and an asynchronous clear input for immediate resetting of all outputs. This makes it highly versatile for various timing and control logic applications. With fast propagation delay and robust design, the 74161 is commonly used in digital timers, frequency dividers, and programmable counters. Packaged in a standard 16-pin DIP, it’s ideal for breadboard and PCB use in both academic and industrial electronics projects. Featured By RoboticsBD.
