Working Principles

The CD74AC163E is a synchronous 4-bit binary counter. It counts up or down based on the clock input signal. The counter advances by one on each rising edge of the clock signal when the Count Enable (CE) input is high. The Master Reset (MR) input resets the counter to its initial state when activated. The Parallel Data (P0-P3) inputs allow for presetting the counter to a specific value. The Terminal Count (TC) output goes high when the counter reaches its maximum count value, indicating an overflow condition.

Detailed Application Field Plans

The CD74AC163E can be used in various digital applications, including:

1. Digital frequency dividers
2. Event counters
3. Time delay generators
4. Frequency synthesizers
5. Pulse width modulators
