Description and Introduction

Hot Swappable 2-Wire Bus Buffer with Stuck Bus Recovery The LTC4304CDD#PBF is a hot swappable 2-wire bus buffer manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Manufacturer:** LINEAR (Linear Technology)  
- **Part Number:** LTC4304CDD#PBF  
- **Package:** 8-DFN (3x3mm)  
- **Operating Voltage Range:** 2.7V to 5.5V  
- **I²C/SMBus Compliant:** Yes  
- **Bus Capacitance Buffering:** Up to 400pF  
- **Enable Pin:** Allows for bus isolation  
- **Rise Time Accelerators:** Improves signal integrity  
- **Low Quiescent Current:** 1.5mA (typical)  
- **Operating Temperature Range:** 0°C to 70°C  

### **Descriptions:**  
The LTC4304CDD#PBF is a bidirectional buffer designed to isolate capacitance and support hot swapping in I²C and SMBus systems. It prevents bus lock-up issues and provides level shifting between different voltage domains.  

### **Features:**  
- **Hot Swappable:** Allows insertion/removal of cards without bus disruption  
- **Level Translation:** Supports mixed-voltage I²C buses (2.7V to 5.5V)  
- **Stuck Bus Recovery:** Automatically resets if SDA/SCL lines are stuck low  
- **Precharge Circuitry:** Prevents bus disturbances during live insertion  
- **High Noise Immunity:** Robust against transient disturbances  
- **Small Footprint:** 8-pin DFN package for space-constrained applications  

This device is commonly used in servers, telecom systems, and other applications requiring I²C/SMBus buffering and hot swap capability.
