Description and Introduction

Level Shifting Low Offset Hot Swappable 2-Wire Bus Buffer with Stuck Bus Recovery The LTC4309CGN#PBF is a hot swappable 2-wire bus buffer manufactured by Linear Technology (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** LINEAR (Linear Technology)  
- **Part Number:** LTC4309CGN#PBF  
- **Type:** Hot Swappable 2-Wire Bus Buffer  
- **Operating Voltage Range:** 2.7V to 5.5V  
- **I²C Bus Capacitance Buffering:** Up to 400pF  
- **Maximum Data Rate:** 400kHz (Fast Mode)  
- **Low Quiescent Current:** 1.5mA (typical)  
- **ESD Protection:** ±8kV (Human Body Model)  
- **Package:** 16-Lead SSOP  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
The LTC4309CGN#PBF is a hot-swappable I²C/SMBus buffer that allows insertion and removal of I²C cards without disrupting the system bus. It provides bidirectional buffering, preventing data corruption during live board insertion. The device features rise time accelerators to improve signal integrity and supports level translation between different voltage buses (2.7V to 5.5V).

### **Features:**
- **Hot Swappable:** Enables safe insertion/removal of I²C cards without bus disruption.  
- **Level Translation:** Works across 2.7V to 5.5V buses.  
- **Rise Time Accelerators:** Improves signal integrity for heavily loaded buses.  
- **Stuck Bus Recovery:** Automatically releases the bus if SDA or SCL lines are stuck low.  
- **Precharge Circuitry:** Prevents bus disturbances during live insertion.  
- **Low Offset Voltage:** Minimizes timing delays in buffered signals.  
- **Wide Operating Temperature Range:** -40°C to +85°C.  

This information is strictly based on the manufacturer's datasheet and technical documentation.
