Description and Introduction

Level Shifting Hot Swappable 2-Wire Bus Buffer with Enable The LTC4300A-3CDD#PBF is a hot swappable 2-wire bus buffer manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Part Number:** LTC4300A-3CDD#PBF  
- **Manufacturer:** LINEAR (Linear Technology)  
- **Package:** 8-DFN (3x3mm)  
- **Operating Voltage Range:** 2.7V to 5.5V  
- **I²C/SMBus Compatible**  
- **Low Offset Voltage:** ≤30mV  
- **High Noise Margin:** Supports up to 400kHz bus speeds  
- **Rise Time Accelerators** for improved signal integrity  
- **Stuck Bus Recovery:** Automatically releases bus lines if stuck low  
- **ESD Protection:** ±8kV HBM on SDA/SCL pins  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The LTC4300A-3CDD#PBF is a 2-wire bus buffer that provides capacitance buffering, rise time acceleration, and level translation for I²C and SMBus systems. It prevents bus lock-up and supports hot swapping, allowing boards to be inserted or removed without disrupting communication.  

### **Features:**  
- **Hot Swappable:** Enables live insertion/removal of I²C devices  
- **Level Shifting:** Works across mixed-voltage systems (2.7V to 5.5V)  
- **Prevents Bus Lock-Up:** Automatically disconnects if bus lines are stuck low  
- **Low Supply Current:** Typically 1.5mA  
- **Backdrive Protection:** Prevents damage during hot plugging  
- **Compatible with 400kHz I²C and SMBus Standards**  

This device is commonly used in multi-master I²C systems, server backplanes, and other applications requiring robust bus buffering.
