Description and Introduction

3.3-V ABT Octal Bus Transceivers With 3-State Outputs The SN74LVTH245ADBR is a 3.3-V ABT octal bus transceiver manufactured by Texas Instruments. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TEXAS)  
- **Type:** Octal Bus Transceiver  
- **Technology:** 3.3-V ABT (Advanced BiCMOS Technology)  
- **Supply Voltage Range:** 2.7 V to 3.6 V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Number of Channels:** 8 (Octal)  
- **Logic Family:** LVTH (Low-Voltage BiCMOS with TTL-Compatible Inputs)  
- **Output Type:** 3-State  
- **Package Type:** SSOP (Shrink Small Outline Package)  
- **Package / Case:** SSOP-20  
- **Mounting Type:** Surface Mount  
- **Data Rate:** Up to 200 Mbps  
- **Input/Output Compatibility:** 5V Tolerant Inputs  

### **Descriptions:**  
- The SN74LVTH245ADBR is a bidirectional octal bus transceiver designed for asynchronous communication between data buses.  
- It features non-inverting 3-state outputs and is compatible with TTL input and output levels.  
- The direction of data flow is controlled by the DIR (Direction Control) input, while the Output Enable (OE) input disables the outputs when high.  

### **Features:**  
- **Bidirectional Voltage Translation:** Supports mixed 3.3V and 5V systems.  
- **3-State Outputs:** Allows multiple devices to share a common bus.  
- **Bus-Hold on Data Inputs:** Eliminates the need for external pull-up/pull-down resistors.  
- **Live Insertion Protection:** Supports hot insertion without causing bus disruption.  
- **ESD Protection:** Exceeds 2000 V per JESD 22-A114.  
- **Low Power Consumption:** Optimized for 3.3V operation.
