Working Principles

The 74HC4520D,112 is a binary ripple counter that counts the number of clock pulses received. It has an asynchronous master reset (MR) input that resets the counter to zero when activated. The clock pulse (CP) input increments the counter by one on each rising edge. The outputs (Q0-Q9) represent the binary count value. When the terminal count (TC) output goes high, it indicates that the counter has reached its maximum value.

Detailed Application Field Plans

The 74HC4520D,112 can be used in various applications, including: 1. Frequency division in digital communication systems 2. Event counting in industrial automation 3. Time measurement in electronic timers 4. Pulse generation in waveform generators 5. Clock signal generation in microcontrollers
