Working Principles

SN74HC4040NSRE4 operates as a binary ripple counter by counting clock transitions. The counter advances by one on each rising edge of the clock input. The master reset input allows the counter to be cleared to its initial state. The outputs represent the binary count, with Q12 being the least significant bit and Q4 being the most significant bit. The ripple carry output provides a signal when the counter reaches its maximum count, allowing for cascading multiple counters.
