The HD74LS92P is a high-speed, low-power Schottky device containing four master-slave flip-flops and additional gating. It is designed to provide a divide-by-two counter and a three-stage binary counter for divide-by-six operations. To achieve a maximum divide-by-twelve count length, the B input must be externally connected to the QA output.
✅Features
- Dual Counter Functionality
- High-Speed Operation
- Low Power Consumption
- Integrated Reset
- Flexible Count Length
