### **Descriptions:**  
- The TC74VHCV573FT is an octal D-type latch with 3-state outputs, designed for bus interface applications.  
- It features a latch enable (LE) input and an output enable (OE) input for controlling data flow.  
- The device operates at high speed while maintaining low power consumption typical of CMOS technology.  
- It is compatible with TTL levels, making it suitable for mixed-voltage systems.  

### **Features:**  
- **Wide Operating Voltage Range:** 2.0V to 5.5V  
- **High-Speed Operation:** tpd = 4.7 ns (max) at 5V  
- **3-State Outputs:** Allows direct connection to a bus  
- **Balanced Propagation Delays:** Ensures stable performance  
- **Low Power Consumption:** ICC = 4 μA (max) at 25°C  
- **TTL-Compatible Inputs:** Can interface with TTL logic levels  
- **Latch-Up Performance:** Exceeds 300 mA per JESD 78  
- **ESD Protection:** HBM 2000V (min), MM 200V (min)  

The TC74VHCV573FT is commonly used in data storage, bus interfacing, and signal buffering applications.
