74HC161 4-Bit Binary Counter

The 74HC161 is a high-speed CMOS 4-bit synchronous binary counter in a DIP-16 package. It offers clear, load, and enable inputs for precise counting control. This IC counts upward on each clock pulse and can be easily cascaded for higher bit counting.

Its TTL-compatible inputs and outputs allow seamless integration with microcontrollers, digital logic circuits, and other 74-series ICs. The synchronous design ensures reliable, glitch-free operation, even at high clock speeds.

Common applications include event counting, frequency division, digital timers, and sequence generation. With low power consumption and robust performance, the 74HC161 is ideal for both educational projects and professional designs. The DIP-16 format makes it breadboard-friendly and easy to use in PCB layouts.
