Description and Introduction

20-Bit Dual Supply Bus Transceiver with Configurable Voltage Translation and 3-State Outputs The SN74AVC20T245DGVR is a 20-bit dual-supply bus transceiver manufactured by Texas Instruments (TI).  

### **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:** TVSOP (DGVR) – 56-pin  
- **Data Rate:** Up to 380 Mbps  
- **I/O Type:** Tri-state, non-inverting  
- **Direction Control:** DIR pin for data flow control  
- **Voltage Translation:** Bidirectional voltage translation between different supply levels  

### **Descriptions:**  
The SN74AVC20T245DGVR is a bidirectional voltage-level translator designed for mixed-voltage applications. It allows seamless communication between devices operating at different voltage levels (1.2V to 3.6V). It features dual-supply architecture, enabling voltage translation with automatic direction sensing.  

### **Features:**  
- **Bidirectional Voltage Translation:** Supports 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V supply levels.  
- **Partial Power-Down Protection:** I/O ports tolerate voltages when power is off.  
- **Low Power Consumption:** Optimized for battery-powered applications.  
- **Overvoltage-Tolerant Inputs/Outputs:** Up to 3.6V on either supply rail.  
- **ESD Protection:** Exceeds 2000V HBM (Human Body Model).  
- **Direction Control:** DIR pin determines data flow (A to B or B to A).  
- **High-Speed Operation:** Supports up to 380 Mbps data rates.  

This device is commonly used in mixed-voltage systems, such as microcontrollers, FPGAs, and communication interfaces.
