Description and Introduction

Hot Swappable 2-Wire Bus Buffers 8-SOIC -40 to 85 The TCA4311DRG4 is a hot swappable I²C bus buffer manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Supply Voltage Range:** 2.7V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **I²C Bus Capacitance Buffering:** Up to 400 pF  
- **Maximum Data Rate:** 400 kHz (Fast-mode I²C)  
- **Low Standby Current:** 1 µA (typical)  
- **ESD Protection:** ±8 kV HBM (Human Body Model)  
- **Package:** SOIC-8  

### **Descriptions:**  
- The TCA4311DRG4 is a bidirectional buffer that isolates capacitance on the I²C bus, allowing longer traces and more devices.  
- It supports hot-swapping by providing rise-time acceleration and voltage level translation between 2.7V and 5.5V buses.  
- The device features an enable (EN) pin for power management and bus isolation.  

### **Features:**  
- **Hot-Swap Capability:** Allows insertion/removal of cards without bus disruption.  
- **Bidirectional Buffering:** Isolates bus capacitance while maintaining signal integrity.  
- **Voltage Level Translation:** Works across mixed-voltage systems (2.7V to 5.5V).  
- **Rise-Time Accelerators:** Improves signal integrity for long bus lines.  
- **Low-Power Mode:** Enabled via the EN pin to reduce power consumption.  

This information is based solely on TI's official documentation for the TCA4311DRG4.
