Working Principles

The MC14028BDR2 is a synchronous 4-bit binary counter. It operates by counting the number of clock pulses received on the Clock Input pin. The counter can be reset to its initial state using the Reset Input pin. The Enable Input pin allows for enabling or disabling the counting operation.

The counter has four data input pins (A, B, C, D) which determine the initial count value. The counter outputs the current count value on the four data output pins (A, B, C, D). Additionally, it provides carry and borrow outputs for cascading multiple counters together.

Detailed Application Field Plans

The MC14028BDR2 is commonly used in various digital counting applications, including:

1. Frequency dividers
2. Event counters
3. Timer circuits
4. Digital clocks
5. Industrial automation systems
