### **Descriptions:**
- The TC74HC273 is an 8-bit D-type flip-flop with a common clock (CP) and master reset (MR).
- It features edge-triggered operation, where data is transferred to the outputs on the positive edge of the clock pulse.
- The master reset (MR) input asynchronously clears all flip-flops when driven low.
- Suitable for applications requiring data storage, synchronization, or buffering.
### **Features:**
- **High-Speed Operation:** Optimized for fast switching applications.
- **Low Power Consumption:** CMOS technology ensures low power dissipation.
- **Wide Operating Voltage Range:** Supports 2V to 6V operation.
- **High Noise Immunity:** CMOS design provides robust noise resistance.
- **Octal Flip-Flop:** Eight independent D-type flip-flops in a single package.
- **3-State Outputs:** Not applicable (standard outputs only).
- **Asynchronous Master Reset:** Clears all outputs when activated.
