Working Principles
The 74LVC169PW,112 is a synchronous binary up/down counter. It operates based on the input clock signal (CLK) and the Up/Down (U/D) control signal. When U/D is high, the counter increments its value on each rising edge of CLK. Conversely, when U/D is low, the counter decrements its value on each rising edge of CLK. The outputs (QA-QD) represent the current count value.
