Description and Introduction

32-Bit Buffer/Driver With 3-State Outputs The **SN74LVCH32244AZKER** is a 32-bit buffer/driver from Texas Instruments (TI). Here are its key specifications, descriptions, and features:

### **Manufacturer:**  
Texas Instruments (TI)  

### **Specifications:**  
- **Logic Type:** Buffer/Driver  
- **Number of Bits:** 32  
- **Output Type:** 3-State  
- **Voltage Supply Range:** 1.65V to 3.6V  
- **High-Speed Operation:** 3.6V tpd ~ 4.3ns  
- **Input/Output Compatibility:** 5V Tolerant Inputs  
- **Drive Capability:** ±24mA Output Drive at 3.3V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 96-Ball NFBGA (ZKE)  

### **Descriptions:**  
- Designed for 1.65V to 3.6V VCC operation.  
- Supports partial power-down mode with bus hold.  
- Provides high-speed signal buffering and driving for bus applications.  

### **Features:**  
- **Bus Hold on Data Inputs** – Eliminates the need for external pull-up/pull-down resistors.  
- **3-State Outputs** – Allows multiple devices to share a common bus.  
- **5V-Tolerant Inputs** – Enables interfacing with 5V logic signals.  
- **Low Power Consumption** – Optimized for battery-operated applications.  
- **ESD Protection** – Exceeds 2000V HBM (Human Body Model).  

This device is commonly used in digital systems requiring high-speed buffering and bus driving with low power consumption.

Application Scenarios & Design Considerations

32-Bit Buffer/Driver With 3-State Outputs

Alternative Part Number

  • 74LVC32244AEC,518 --: Same 32-bit LVC bus-interface function in a comparable BGA package, with 3.3V operation and 5V-tolerant inputs, making it a close functional drop-in.
  • 74LVCH32244AEC,518 --: Bus-hold variant of the 32-bit LVC transceiver family, matching the 'H' bus-hold feature of the original and suitable for the same 3.3V bus-interface applications.
  • 74LVC32245AEC,518 --: 32-bit LVC bus transceiver with similar voltage, drive, and package characteristics; pin/function differences should be verified, but it is a practical alternate source for the same application class.
