Description

A set of 5 x SN74HC161N High-Speed CMOS 4-Bit Synchronous Binary Counter ICs in DIP-16 package, ideal for high-speed counting, timing, and digital control applications.

The SN74HC161N is a synchronous, presettable 4-bit binary counter featuring an internal carry look-ahead for fast counting designs. All flip-flops are clocked simultaneously, ensuring outputs change together and eliminating the counting spikes associated with ripple counters. A buffered CLK input triggers counting on the rising edge of the clock signal.

Perfect for repairs, prototyping, education, and DIY electronics projects.
