Working Principles

The SN74HC161PWR is a synchronous 4-bit binary counter that operates based on the input clock signal. The counter advances its count by one on each rising edge of the clock when the count enable input (CPD) is high. The parallel enable input (PE) allows loading of data into the counter asynchronously, while the master reset input (MR) resets the counter to its initial state.

Detailed Application Field Plans

The SN74HC161PWR can be used in various digital applications, including but not limited to: 1. Frequency division circuits 2. Event counters 3. Digital clocks and timers 4. Industrial control systems 5. Data processing units
