Description and Introduction

20 BIT DUAL SUPPLY BUS TRANSCEIVER WITH CONFIGURABLE VOLTAGE TRANSLATION AND 3-STATE OUTPUTS The SN74AVC20T245GQLR is a 20-bit dual-supply bus transceiver manufactured by Texas Instruments (TI).  

### **Key Specifications:**  
- **Technology:** AVC (Advanced Very-Low-Voltage CMOS)  
- **Number of Bits:** 20  
- **Supply Voltage Range (VCCA):** 1.2V to 3.6V  
- **Supply Voltage Range (VCCB):** 1.2V to 3.6V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** BGA (MicroStar Junior™)  
- **Data Rate:** Up to 380 Mbps  
- **I/O Type:** 3-State Outputs  
- **Direction Control:** DIR (Direction Control Pin)  

### **Descriptions and Features:**  
- **Bidirectional Voltage Translation:** Allows voltage level shifting between two different supply voltages (VCCA and VCCB).  
- **Partial Power-Down Mode (Ioff):** Supports live insertion by preventing backflow current when powered off.  
- **3-State Outputs:** Enables high-impedance state for bus isolation.  
- **Low Power Consumption:** Optimized for power-sensitive applications.  
- **ESD Protection:** Exceeds 2000V HBM (Human Body Model) for robustness.  
- **Auto-Direction Sensing (Optional):** Some variants support automatic direction sensing.  

This device is commonly used in mixed-voltage systems, such as interfacing between processors, FPGAs, and low-voltage peripherals.
