Description:
The M74HC161B1R Synchronous Binary Counter IC – Pack of 5 is a high-speed CMOS logic chip containing a 4-bit synchronous binary counter with clear, load, and enable functions. Designed for general-purpose counting applications, it increments binary output on each rising clock edge, enabling precise and programmable count sequences in digital circuits.
Operating over a voltage range of 2V to 6V and compatible with TTL input levels, the M74HC161B1R is ideal for timing, frequency division, digital state machines, and sequencing systems. With synchronous clear and load features, as well as asynchronous master reset, it provides full control over the counter’s operation. Packaged in a DIP-16 format, this IC is easily implemented on breadboards and through-hole PCBs for prototyping and production use alike.
