Working Principles

SN74HC4020PW operates based on the principle of binary counting. The clock input (CP) triggers the counter to increment by one on each rising edge. The output stages represent the binary count, with Q0 being the least significant bit (LSB) and Q13 being the most significant bit (MSB). The master reset input (MR) allows for synchronous reset of the counter to zero.
