The CD74HC4040E is an integrated circuit (IC) component that belongs to the HC family of high-speed CMOS logic devices. It is a 12-stage binary ripple counter with an asynchronous reset function. Here is an overview of the CD74HC4040E along with its key features:
1. High-Speed Operation: The CD74HC4040E is designed to operate at a high-speed clock frequency, making it suitable for applications requiring quick counting capabilities. It can handle clock frequencies of up to 28 MHz.
2. 12-Stage Binary Ripple Counter: This IC component features 12 stages or flip-flops, making it capable of counting up to 4096 (2^12) different binary values. It counts in a ripple fashion, with each stage triggering the next stage based on the clock input.
3. Asynchronous Reset: The CD74HC4040E includes an asynchronous reset function, allowing users to reset the counter to a predefined value at any time without needing to wait for a specific clock cycle. This feature enhances flexibility and control over the counting process.
4. Schmitt Trigger Inputs: The IC utilizes Schmitt trigger inputs, which provide hysteresis and enhance noise immunity. This ensures that the circuit maintains stable and reliable operation, even in the presence of input signal fluctuations or noise.
5. Wide Operating Voltage Range: The CD74HC4040E can operate within a wide voltage range, from 2 to 6 volts
