Working Principles

The CD4029BPWR is a synchronous binary counter/divider that operates based on the clock signal. On each rising edge of the clock, the counter increments by one, following the binary sequence. The counter can be reset asynchronously using the reset input or loaded with a specific value in parallel using the parallel load input. The carry output provides a signal when the counter reaches its maximum value.
