An SN74HC161N Synchronous 4-Bit Binary Counter is a high-speed CMOS logic Integrated Circuit (IC) designed for fast counting, frequency division, and digital timing applications. Encapsulated in a standard 16-pin Dual In-line Package (DIP-16), it features internal look-ahead carry logic for high-speed synchronous operation where all flip-flops trigger simultaneously on the rising edge of the clock signal. Printed clearly with part number "SN74HC161N", it includes synchronous parallel loading capability, enable inputs for easy cascading, and an active-LOW asynchronous master reset that immediately clears all outputs to logic LOW.

This product is featured by Famephase Electronic Accessories as an essential digital logic component for binary counters, clock frequency dividers, state machine sequencers, digital timers, and address generators.
