- **Low-Level Output Current:** 24mA  
- **Propagation Delay Time (Max):** 9.5ns at 5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package / Case:** SOIC-20 (DWR)  
- **Mounting Type:** Surface Mount  

### **Descriptions:**  
The SN74AC373DWR is an octal transparent latch with 3-state outputs designed for 2V to 6V VCC operation. It is commonly used in bus interface applications where data must be temporarily stored or buffered.  

### **Features:**  
- **3-State Outputs** for bus-oriented applications  
- **Latch-Up Performance** exceeds 250mA per JESD 17  
- **ESD Protection** exceeds JESD 22 (2000-V Human-Body Model)  
- **Wide Operating Voltage Range (2V to 6V)**  
- **Balanced Propagation Delays**  
- **High-Current Outputs (Up to ±24mA)**  
- **Flow-Through Pinout** for optimized PCB layout  

This information is sourced from TI's official datasheet.

Application Scenarios & Design Considerations

Octal D-Type Transparent Latches With 3-State Outputs

Alternative Part Number

  • MC74AC373DWR2 --: Same AC-series octal transparent D-type latch with 3-state outputs in a 20-pin SOIC wide-body package, directly pin-compatible and functionally equivalent to the SN74AC373DWR.
  • 74AC373SCX --: AC-family octal latch with 3-state outputs in SOIC-20, matching logic function, supply range, and pinout for a drop-in replacement.
  • CD74AC373M96 --: TI AC-family octal transparent latch in SOIC-20 with equivalent function and pinout, though the CD prefix series differs from the SN74 series naming.
