Description
The 74HC4040 is a high-speed, silicon-gate CMOS 12-Stage Binary Ripple Counter. The device consists of 12 master-slave flip-flops connected in series. The output of each stage advances on the negative-going transition of the preceding stage’s clock, creating a ripple effect where the counter updates sequentially.
This IC features a buffered clock input (CP) and a common asynchronous master reset (MR) input that clears all stages to a zero state when taken HIGH. It is widely used in frequency division, time-delay circuits, and digital counter applications where a binary output representing the number of pulses is required.
