Description and Introduction

Single-Bit Dual-Supply Bus Transceiver with Configurable Voltage Translation and 3-State Outputs The **SN74AVCH1T45DBVR** is a single-bit dual-supply bus transceiver manufactured by **Texas Instruments (TI)**. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Technology Family:** AVC  
- **Supply Voltage Range (VCC):** 1.2V to 3.6V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Number of Channels:** 1  
- **Data Rate:** Up to 500 Mbps  
- **Input/Output Type:** 3-State  
- **Package Type:** SOT-23-6 (DBV)  
- **Logic Voltage (VCCA/VCCB):** 1.2V to 3.6V (independent supplies)  
- **Propagation Delay:** 2.5 ns (typical at 3.3V)  
- **I/O Standards:** Supports mixed-mode voltage operation  

### **Description:**  
The SN74AVCH1T45DBVR is a **single-bit, dual-supply, non-inverting bus transceiver** designed for asynchronous communication between data buses operating at different voltage levels. It features **auto-direction sensing**, eliminating the need for a direction control signal.  

### **Features:**  
- **Bidirectional Voltage-Level Translation:** Allows interfacing between different voltage nodes (1.2V to 3.6V).  
- **Partial Power-Down Protection:** I/Os remain in high-impedance state when either VCC is at GND.  
- **3-State Outputs:** Supports bus isolation.  
- **Low Power Consumption:** Typical ICC of <10 µA.  
- **ESD Protection:** Exceeds 2000V HBM per JESD22-A114.  
- **No Direction Control Needed:** Automatically detects data flow direction.  

This device is commonly used in applications such as **portable electronics, IoT devices, and mixed-voltage systems**.
