Working Principles

The MC14521BDR2G is a binary counter with synchronous reset. It counts the number of clock pulses applied to its input pins and provides corresponding outputs. The synchronous reset feature allows the counter to be easily initialized to a specific value. The counter advances on each rising edge of the clock signal, and the outputs represent the binary representation of the count value.

Detailed Application Field Plans

1. Frequency Division: The MC14521BDR2G can be used to divide the frequency of an input signal by a specific factor, allowing for frequency reduction in various applications such as clock generation circuits.
2. Event Counting: The counter can be utilized to count events or occurrences in systems where precise event tracking is required, such as in industrial automation or scientific experiments.
3. Timekeeping: By connecting the counter to a clock source, it can be employed to measure time intervals or generate time-based signals in applications like timers or clocks.
