Disadvantages: - Limited number of bits (4-bit) - Requires external clock signal

Working Principles

The CD74HCT161M96G4 is a synchronous 4-bit binary counter. It counts in a binary sequence from 0000 to 1111 and then resets back to 0000. The counting is controlled by an external clock signal applied to the CP (Clock Pulse) input. When the CP input transitions from low to high, the counter increments by one. The MR pin can be used to reset the counter to its initial state (0000). The CE pin enables or disables counting, while the TC pin indicates when the counter reaches its maximum value.

Application Field Plans

The CD74HCT161M96G4 is widely used in various digital applications that require counting functionality. Some potential application fields include:

1. Digital frequency dividers
2. Event counters
3. Timekeeping circuits
4. Address generation in memory systems
5. Industrial automation systems
6. Communication equipment
