The IC component 74HC390D,652 is a high-speed CMOS integrated circuit that incorporates two 4-stage binary ripple counters with a single master reset. Here are some key features and characteristics of this component:
1. High-speed operation: The 74HC390D,652 operates at a high frequency range, making it suitable for applications that require quick counting or timekeeping.
2. Dual 4-stage binary ripple counters: This IC component consists of two separate counters, each with four stages. These counters can be cascaded together for applications that require higher counting stages.
3. Master reset: The IC includes a master reset pin (MR) that can be used to reset both counters simultaneously. This feature allows for easy initialization or synchronization of the counters.
4. Separate clock inputs: Each counter has its own clock input (CP0 and CP1), which allows for independent clocking of the counters. This feature enables different counting rates or asynchronous operation between the two counters.
5. Ripple-carry output: The IC provides a ripple-carry output (RC0 and RC1) for each counter, allowing the cascading of multiple ICs to achieve larger counting stages.
6. Schmitt-trigger inputs: The inputs of the 74HC390D,652 incorporate Schmitt-trigger technology, providing improved noise immunity and hysteresis for better performance in noisy environments
