Description and Introduction

3.3-V ABT Octal Bus Transceivers With 3-State Outputs The SN74LVT245BDWR is a 3.3V octal bus transceiver manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** Octal Bus Transceiver  
- **Voltage Supply:** 3V to 3.6V (3.3V nominal)  
- **Input/Output Type:** 3-State  
- **Number of Channels:** 8  
- **High-Speed Operation:** 3.5 ns max (tpd at 3.3V)  
- **Output Drive Capability:** ±32 mA (at 3V VCC)  
- **ESD Protection:** Exceeds 2000V per JESD 22  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** SOIC (DW)  
- **Pin Count:** 20  

### **Descriptions:**  
The SN74LVT245BDWR is a bidirectional transceiver designed for asynchronous communication between data buses. It allows data transmission from A to B or B to A, depending on the direction control (DIR) input. The output-enable (OE) input disables the outputs when high.  

### **Features:**  
- **Bi-Directional Voltage Translation:** Supports mixed-voltage systems  
- **Live Insertion/Withdrawal Protection:** Supports hot-swapping  
- **Bus-Hold Data Inputs:** Eliminates the need for external pull-up/pull-down resistors  
- **Power-Up 3-State Outputs:** Prevents bus contention during power-up  
- **Latch-Up Performance:** Exceeds 500 mA per JESD 78  

This device is commonly used in data communication systems, networking equipment, and other applications requiring bidirectional level shifting.
