The component 74HC390D,653 is a dual 4-bit decade ripple counter. It is a part of the 74HC family, which is a popular series of integrated circuits widely used in digital electronics.
Key Features:
1. Dual 4-bit Decade Counter: The 74HC390D,653 IC comprises two individual, independent counters, each capable of counting in a decade sequence (0 to 9) with ripple carry output.
2. Ripple Carry Output: One of the crucial features of this component is its ripple carry output. It provides a way to cascade multiple counters together, allowing for extended counting capabilities.
3. Asynchronous Reset: The IC includes an asynchronous reset input (RST), which allows for resetting the counter to zero irrespective of the clock input or count enable inputs.
4. Clock Inputs: The 74HC390D,653 operates on an external clock signal. It has two clock inputs, namely CP0 and CP1, for each counter. These clocks trigger the counting sequence when a positive edge or transition occurs.
5. Count Enable Inputs: Each counter has an independent count enable input (ENP and ENT). These inputs control the counting functionality. When enabled, they allow the counter to progress, and when disabled, they freeze the counting process.
6. Low Power Consumption: This IC is designed to consume low power, making it suitable for battery-operated devices or power-sensitive applications
