### **Descriptions:**
The TC74VHC574FK is an octal edge-triggered D-type flip-flop with 3-state outputs. It features a common clock (CP) and output enable (OE) control. On the positive edge of the clock, data from the D inputs is transferred to the Q outputs. The outputs can be placed in a high-impedance state using the OE input.
### **Features:**
- **High-Speed Operation:** tpd = 5.5ns (max) at 5V
- **Low Power Consumption:** ICC = 4μA (max) at 5.5V
- **Wide Operating Voltage Range:** 2.0V to 5.5V
- **3-State Outputs:** Allows bus-oriented applications
- **Balanced Propagation Delays:** Ensures reliable performance
- **Pin-Compatible with 74-Series Logic ICs**
- **ESD Protection:** HBM ≥ 2000V
