Working Principles

The SN74AS163NSRE4 is a synchronous 4-bit binary counter. It counts up or down based on the clock input and control signals. The counter can be preset using the parallel load input, and it can be cleared asynchronously using the clear input. The enable inputs control the count and parallel load operations. The counter advances on each rising edge of the clock signal when the enable count input is active. The outputs represent the current count value in binary format.

The SN74AS163NSRE4 can be used in various applications that require counting functionality. Some potential application fields include:

1. Digital frequency dividers
2. Event counters
3. Timekeeping circuits
4. Industrial automation systems
5. Communication equipment
6. Automotive electronics
7. Consumer electronics
