### **Descriptions:**  
The SN74ALS573CDW is an octal transparent D-type latch with 3-state outputs designed for bus-organized systems. It features a latch-enable (LE) input for data storage and an output-enable (OE) input for 3-state control, allowing the outputs to be placed in a high-impedance state.  

### **Features:**  
- **Octal D-Type Latches** with 3-State Outputs  
- **Bus-Structured Pinout**  
- **Buffered Control Inputs** (LE and OE)  
- **High-Impedance State** for bus-oriented applications  
- **Wide Operating Voltage Range** (4.5V to 5.5V)  
- **Low Power Consumption** (ALS Series)  
- **ESD Protection** on all inputs and outputs  
- **Compatible with TTL Inputs**  

This information is strictly based on the manufacturer's specifications and datasheet.

Application Scenarios & Design Considerations

Octal D-Type Transparent Latches With 3-State Outputs

Alternative Part Number

  • 74ACT573SCX --: Octal D-type transparent latch with 3-state outputs in SOIC-20, functionally equivalent to the SN74ALS573 with faster ACT CMOS speed and compatible pinout.
  • MC74ACT573DWG --: Same octal transparent latch function in a wide-body SOIC-20 package, direct functional and pin-compatible replacement for the ALS573.
  • CD74ACT573M --: TI ACT-series octal transparent D-latch with 3-state outputs in SOIC-20, same logic function and pinout as the original ALS device.
