HLF 74HC161 Presettable Synchronous 4-Bit Binary Counter with Asynchronous Reset – DIP16 | High-Speed CMOS Logic | 2V–6V, -40°C to +85°C | Through-Hole Package

The HLF 74HC161 is a high-speed CMOS presettable synchronous 4-bit binary counter featuring an asynchronous master reset. It is designed for use in high-speed counting, frequency division, and sequencing applications. The counter increments synchronously with the clock and can be preset to any binary value using its parallel load inputs.

The asynchronous master reset clears the counter immediately, ensuring fast and predictable reset control. Operating over a 2V–6V range and a temperature span of -40°C to +85°C, the DIP16 through-hole package ensures low power consumption, excellent noise immunity, and reliable operation for industrial and embedded logic applications.
