4-Channel, 2-Wire Bus Multiplexer with Capacitance Buffering

Partnumber Manufacturer Quantity Availability
LTC4306IGN LTC 39 In Stock

Description and Introduction

4-Channel, 2-Wire Bus Multiplexer with Capacitance Buffering The LTC4306IGN is a hot swappable 2-wire bus buffer designed to provide capacitance buffering and rise time acceleration for I²C and SMBus applications.  

### **Key Features:**  
- **Hot Swappable:** Allows insertion/removal of cards without disturbing the I²C bus.  
- **Level Shifting:** Supports mixed-voltage systems (2.7V to 5.5V).  
- **Rise Time Accelerators:** Improves signal integrity by reducing rise times.  
- **Stuck Bus Recovery:** Automatically releases the bus if SDA or SCL is stuck low.  
- **Low Offset Voltage:** Minimizes timing skew between SDA and SCL.  
- **High Noise Margin:** Improves noise immunity in electrically noisy environments.  
- **Wide Supply Range:** Operates from 2.7V to 5.5V.  
- **Package:** 16-Lead SSOP (IGN).  

### **Applications:**  
- Servers and storage systems  
- Hot-swappable I²C cards  
- Multi-voltage I²C systems  
- Industrial and telecom equipment  

This buffer helps maintain signal integrity while isolating bus capacitance, preventing corruption during live insertion.

Description and Introduction

4-Channel, 2-Wire Bus Multiplexer with Capacitance Buffering The LTC4306IGN is a hot-swappable 2-wire bus buffer manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Manufacturer:** Linear Technology (Analog Devices)  
- **Part Number:** LTC4306IGN  
- **Package:** 16-Lead SSOP  
- **Operating Voltage Range:** 2.7V to 5.5V  
- **I²C Bus Capacitance Buffering:** Isolates capacitance to allow more devices on the bus  
- **Rise Time Accelerators:** Improves bus speed by actively pulling up signals  
- **Hot-Swap Capability:** Allows insertion/removal of cards without bus disruption  
- **Low Quiescent Current:** Typically 1mA  
- **Operating Temperature Range:** -40°C to +85°C  
- **Bus Voltage Range:** 0V to 5.5V  

### **Descriptions and Features:**  
- **2-Wire Bus Buffer:** Compatible with I²C and SMBus systems.  
- **Prevents Bus Locks:** Prevents stuck bus conditions during live board insertion.  
- **Level Shifting:** Supports mixed-voltage systems (2.7V to 5.5V).  
- **Automatic Isolation:** Disconnects bus if power is lost.  
- **High Noise Immunity:** Robust against bus disturbances.  
- **Enable/Disable Control:** Allows manual bus connection/disconnection.  

The LTC4306IGN is designed for applications requiring reliable I²C/SMBus buffering, such as servers, telecom systems, and industrial controllers.
