Description and Introduction

Hot Swappable 2-Wire Bus Buffers 8-VSSOP -40 to 85 The TCA4311DGKRG4 is a hot-swappable I²C bus buffer manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Texas Instruments (TI)  
- **Part Number:** TCA4311DGKRG4  
- **Type:** I²C Bus Buffer  
- **Supply Voltage Range:** 2.7V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** VSSOP-8 (DGK)  
- **Bus Capacitance Buffering:** Supports up to 400 pF on both sides  
- **I²C Bus Voltage Levels:** 2.7V to 5.5V (compatible with mixed-voltage systems)  
- **Enable Pin:** Active-high (EN) for control  
- **Hot-Swappable:** Allows insertion/removal without bus disruption  
- **ESD Protection:** ±2000V HBM (Human Body Model)  

### **Descriptions:**
The TCA4311DGKRG4 is a bidirectional buffer designed for I²C and SMBus applications. It provides capacitance buffering and voltage level translation between different I²C bus segments, preventing bus lock-up and signal degradation. The device supports hot-swapping, making it suitable for live insertion/removal of cards or modules.

### **Features:**
- **Bidirectional Buffer:** Supports I²C clock (SCL) and data (SDA) lines.  
- **Voltage Level Translation:** Works across mixed-voltage systems (2.7V to 5.5V).  
- **Hot-Swap Capability:** Prevents bus disturbances during insertion/removal.  
- **Low Standby Current:** Consumes minimal power when disabled.  
- **High Noise Immunity:** Robust against bus glitches.  
- **Compatibility:** Fully compliant with I²C and SMBus standards.  
- **Small Footprint:** 8-pin VSSOP package for space-constrained designs.  

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