#### **Descriptions:**  
The **SN74LVCH32373AGKER** is a 32-bit transparent latch with 3-state outputs, designed for low-voltage (1.65V to 3.6V) applications. It features 5V-tolerant inputs, allowing interfacing with higher-voltage systems. The outputs can be placed in a high-impedance state for bus-oriented applications.  

#### **Features:**  
- **32-Bit Wide Bus Interface**  
- **5V-Tolerant Inputs/Outputs** for Mixed-Voltage Systems  
- **3-State Outputs** for Bus Driving  
- **Supports Partial Power-Down Mode (IOFF)**  
- **ESD Protection Exceeds 2000V (HBM)**  
- **Balanced Propagation Delays**  
- **Low Power Consumption**  
- **Latch-Up Performance Exceeds 250 mA per JESD 17**  

This device is commonly used in data storage, buffering, and bus interface applications in computing and communication systems.

Application Scenarios & Design Considerations

32-Bit Transparent D-Type Latch With 3-State Outputs

Alternative Part Number

  • 74LVC32373AEC --: Same 32-bit LVC-family bus-hold transparent D-type latch function in a comparable LFBGA package, with similar voltage range and drive strength.
  • 74LCX32373G --: 32-bit low-voltage transparent latch with bus-hold, functionally equivalent to the LVCH32373A and available in BGA-style packaging.
  • 74ALVCH32373BFG --: ALVCH-family 32-bit bus-hold transparent latch offering equivalent logic function and 3.3V operation as a cross-family substitute.
