Description and Introduction

20-BIT DUAL-SUPPLY BUS TRANSCEIVER WITH CONFIGURABLE VOLTAGE TRANSLATION AND 3-STATE OUTPUTS The SN74AVCH20T245GR is a 20-bit dual-supply bus transceiver from Texas Instruments (TI).  

### **Key Specifications:**  
- **Technology:** CMOS  
- **Voltage Supply (VCCA):** 1.2V to 3.6V  
- **Voltage Supply (VCCB):** 1.2V to 3.6V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** VQFN (RGR)  
- **Number of Bits:** 20  
- **Data Rate:** Up to 380 Mbps  
- **I/O Type:** Tri-State, Non-Inverting  

### **Descriptions and Features:**  
- **Dual-Supply Operation:** Allows voltage translation between different supply levels (1.2V to 3.6V).  
- **Direction Control:** Uses DIR (direction control) and OE (output enable) pins for bidirectional data flow.  
- **Partial Power-Down Protection:** I/O ports tolerate voltages up to 3.6V when powered off.  
- **Bus-Hold on Data Inputs:** Eliminates the need for external pull-up/pull-down resistors.  
- **ESD Protection:** Exceeds 2000V HBM (Human Body Model) for robust performance.  
- **Low Power Consumption:** Optimized for power-sensitive applications.  

This transceiver is commonly used in mixed-voltage systems, such as communication interfaces, portable devices, and industrial applications.
