### **Specifications:**  
- **Logic Type:** Octal Transparent D-Type Latch  
- **Number of Bits:** 8  
- **Output Type:** 3-State  
- **Voltage Supply Range:** 4.5V to 5.5V  
- **High-Level Output Current:** -24mA  
- **Low-Level Output Current:** 24mA  
- **Propagation Delay Time:** 10.5ns (max) at 5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC (DW), 20-pin  

### **Descriptions:**  
The SN74ACT573DW features eight D-type latches with 3-state outputs for bus interfacing. It is designed for high-speed, low-power operation in 5V systems. The latch is transparent when the latch enable (LE) input is high, allowing data to pass through. When LE is low, the data is latched. The output enable (OE) input controls the 3-state outputs.  

### **Features:**  
- **3-State Outputs** for bus-oriented applications  
- **High-Speed Operation:** Optimized for 5V systems  
- **Low Power Consumption:** ACT technology  
- **Wide Operating Voltage Range:** 4.5V to 5.5V  
- **Balanced Propagation Delays**  
- **ESD Protection:** Exceeds 2000V per JESD 22  

This latch is commonly used in memory address latching, data buffering, and bus interface applications.
