Description and Introduction

20-Bit Dual Supply Bus Transceiver with Configurable Voltage Translation and 3-State Outputs The SN74AVC20T245DGG is a 20-bit dual-supply bus transceiver manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Technology Family:** AVC  
- **Supply Voltage (VCC):** 1.2V to 3.6V (VCCA, VCCB)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Number of Channels:** 20  
- **Logic Type:** Bus Transceiver  
- **Output Type:** 3-State  
- **Data Rate:** Up to 380 Mbps  
- **Package Type:** TSSOP (DGG)  
- **Pin Count:** 48  

### **Descriptions:**  
- The SN74AVC20T245DGG is a 20-bit non-inverting bus transceiver designed for asynchronous communication between data buses.  
- It supports bidirectional voltage translation between different supply voltages (1.2V to 3.6V).  
- The direction control (DIR) pin determines data flow, while the output enable (OE) pin disables the outputs.  

### **Features:**  
- **Dual-Supply Operation:** Allows voltage translation between two independent voltage supplies (VCCA and VCCB).  
- **Partial Power-Down Protection:** I/Os are disabled when either VCCA or VCCB is at GND.  
- **3-State Outputs:** Supports high-impedance state when disabled.  
- **Low Power Consumption:** Optimized for power-sensitive applications.  
- **ESD Protection:** Exceeds 2000V HBM (Human Body Model).  
- **Wide Voltage Range:** Supports 1.2V to 3.6V on both A and B ports.  

This device is commonly used in mixed-voltage systems, such as communication interfaces, industrial automation, and embedded systems.
