### **Descriptions:**  
The SN74LVC573APWRG4 is an octal transparent latch with 3-state outputs designed for 1.65V to 3.6V VCC operation. It features a latch-enable (LE) input and an output-enable (OE) input for controlling data flow. When LE is high, the Q outputs follow the D inputs. When LE transitions low, the data is latched. The outputs are in a high-impedance state when OE is high.  

### **Features:**  
- **Wide Operating Voltage Range:** 1.65V to 3.6V  
- **Supports Mixed-Mode Voltage Operation**  
- **3-State Outputs for Bus Interface**  
- **Ioff Supports Partial-Power-Down Mode**  
- **Latch-Up Performance Exceeds 250mA per JESD 17**  
- **ESD Protection Exceeds JESD 22 (2000V HBM, 1000V CDM)**  
- **Low Power Consumption (ICC = 10µA max)**  
- **Flow-Through Pinout for Easy PCB Layout**  

This device is commonly used in bus interface, data storage, and signal buffering applications.

Application Scenarios & Design Considerations

Octal Transparent D-Type Latches With 3-State Outputs 20-TSSOP -40 to 125

Alternative Part Number

  • 74LVC573APW,118 --: Same octal D-type transparent latch function with 3-state outputs in TSSOP package, direct functional equivalent from a different manufacturer and series.
  • MC74LCX573DTG --: Low-voltage octal transparent latch with 3-state outputs, comparable LVC-family logic and TSSOP package, suitable drop-in functional replacement.
  • 74LVC573APW --: Octal D-type transparent latch with 3-state outputs in TSSOP, same LVC logic family and pinout, offered under a different brand and naming scheme.
  • SN74LVC573APW --: Identical LVC573A device in the same TSSOP package without the G4 lead-free suffix, offering the same electrical performance and pinout.
