Working Principles

SN74F169N operates based on the principles of digital logic. The clock pulse (CP) controls the counting direction, while the up/down (UP/DOWN) input determines whether the counter counts up or down. The parallel data inputs (P0-P3) allow loading of initial values, and the enable count (ENT) input enables or disables counting. The master reset (MR) input resets the counter to its initial state. The outputs (Q0-Q3) represent the current count value, and the carry output (CE) indicates when the counter reaches its maximum value.
