Description and Introduction

3.3V Quad PECL Receiver The TB3R1D is a Texas Instruments (TI) part, specifically a **3.3-V 4-channel I2C redriving buffer with high drive strength**.  

### **Specifications:**  
- **Supply Voltage (VCC):** 3.3 V  
- **Number of Channels:** 4  
- **Interface:** I²C (I2C)  
- **Drive Strength:** High (supports up to 50 mA sink current per channel)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-pin TSSOP (PW)  

### **Descriptions:**  
- Designed to buffer and redrive I²C signals to extend bus length and reduce signal degradation.  
- Supports **Standard-mode (100 kHz), Fast-mode (400 kHz), and Fast-mode Plus (1 MHz)** I²C speeds.  
- Features **low-voltage operation** (3.3 V) with **high noise immunity**.  

### **Features:**  
- **4-channel I²C buffer** with independent enable control.  
- **High drive strength** for improved signal integrity.  
- **Backdrive protection** on all pins.  
- **Low standby current** consumption.  
- **Hot-swappable** (supports live insertion).  
- **Compatible with I²C and SMBus protocols**.  

This device is commonly used in applications requiring **long I²C bus lengths** or **multiple loads**, such as industrial systems, servers, and embedded designs.
