Description and Introduction

4-Bit Dual-Supply Bus Transceiver with Configurable Voltage Translation and 3-State Outputs 16-UQFN -40 to 85 The SN74AVCH4T245RSVR is a 4-bit dual-supply bus transceiver manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Technology:** CMOS  
- **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  
- **Number of Channels:** 4  
- **Logic Voltage Levels:** 1.2V, 1.5V, 1.8V, 2.5V, 3.3V  
- **Data Rate:** Up to 380 Mbps  
- **Package:** UQFN (RSV) - 16 pins  
- **ESD Protection:** Exceeds 2000V HBM  

### **Descriptions:**  
The SN74AVCH4T245RSVR is a 4-bit non-inverting bus transceiver designed for asynchronous communication between data buses operating at different voltage levels. It features dual supply rails (VCCA and VCCB) to support bidirectional voltage translation between 1.2V and 3.6V systems.  

### **Features:**  
- **Bidirectional Voltage Translation:** Supports mixed-voltage communication between two buses.  
- **Automatic Direction Sensing:** DIR input controls data flow direction.  
- **Partial Power-Down Protection:** I/Os are disabled when either VCC is at GND.  
- **Low Static Power Consumption:** ICC typically < 1µA.  
- **Bus-Hold on Data Inputs:** Eliminates the need for external pull-up/pull-down resistors.  
- **Schmitt-Trigger Inputs:** Improves noise immunity.  
- **Supports Live Insertion:** Allows hot-swapping without signal disruption.  

This device is commonly used in applications requiring level shifting, such as portable electronics, industrial systems, and communication interfaces.
