The 74HC4040D,653 is a 12-stage ripple-carry binary counter integrated circuit (IC). It belongs to the popular 74HC series of ICs, known for its high-speed CMOS logic family. This IC is primarily used for dividing frequencies, time delay generation, and frequency multiplication applications. Here is an overview of its key features:
1. High-speed operation: The 74HC4040D,653 is designed to operate at a high clock frequency, making it suitable for applications that require quick and efficient counting.
2. Binary ripple counter: It is a 12-stage binary ripple counter, meaning that it can count binary numbers from 0 to 4095 (2^12 - 1). Each stage can be considered as a flip-flop, where the output of one stage acts as the clock input for the next stage.
3. Ripple-carry output: The IC features a ripple-carry output (RCO) pin, which provides a signal to indicate an overflow condition. When the counter reaches its maximum count value (4095), the RCO pin goes low, indicating that an overflow has occurred.
4. Synchronous operation: The counter can be reset to zero using the reset (MR) pin. It supports synchronous loading of the initial count by using the parallel data inputs (P0 to P11) and synchronous enable (CE) pin
