The CP82C84A is a versatile integrated circuit (IC) component that serves as a counter and a divider. It offers a range of useful features that make it an essential component in various electronic systems.
One key feature of the CP82C84A is its high-speed counting capability. It can count up to 4,194,303 counts (or roughly 22 bits) before rolling over. This makes it suitable for applications that require accurate and precise counting, such as frequency dividers and event timers.
Additionally, the CP82C84A offers a programmable prescaler, which allows for further division of the input frequency. This feature is beneficial when there is a need to divide high-frequency signals into lower frequencies that are manageable by downstream components. The prescaler supports various division ratios, ranging from 2 to 2^22, providing flexibility in dividing frequencies.
Another notable feature of the CP82C84A is its various operating modes. It can function as a single event counter or as a frequency divider, depending on the selected mode. The integrated control pins enable easy mode selection and configuration, making it adaptable to different application requirements.
The CP82C84A incorporates a Reset input, which allows for the resetting of the counter to a specific value. This is particularly useful in applications that require periodic or conditional counting, where the counter needs to be reset at certain intervals or events.
Furthermore, this IC component is designed to operate in both TTL (Transistor-Transistor Logic) and CMOS (Complementary Metal-Oxide-Semiconductor) logic level environments. This compatibility ensures its seamless integration into various electronic systems, regardless of the logic level compatibility.
Overall, the CP82C84A is a versatile IC component that offers high-speed counting capability, a programmable prescaler, multiple operating modes, and compatibility with TTL and CMOS logic levels. Its features make it a valuable component for a wide range of applications that require accurate counting and frequency division.
