Description and Introduction

3.3-V ABT Octal Bus Transceivers With 3-State Outputs The SN74LVT245BNSR is a 3.3-V ABT octal bus transceiver manufactured by Texas Instruments (TI).  

### **Key Specifications:**  
- **Logic Type:** Octal Bus Transceiver  
- **Voltage Supply:** 3.3V  
- **Number of Bits:** 8  
- **Output Type:** 3-State  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 20-pin SSOP (BNSR)  
- **Data Rate:** Up to 100 MHz  
- **Input/Output Compatibility:** TTL, LVTTL  
- **High Drive Outputs:** ±24 mA at 3.3V  

### **Descriptions and Features:**  
- **Bidirectional Voltage Translation:** Supports mixed-voltage communication between 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-plugging without damaging the device.  
- **ESD Protection:** Exceeds 2000V per JESD 22 (Human Body Model).  
- **Low Power Consumption:** Optimized for 3.3V operation with reduced power dissipation.  

This transceiver is commonly used in data communication systems, networking equipment, and industrial control applications.

Application Scenarios & Design Considerations

3.3-V ABT Octal Bus Transceivers With 3-State Outputs

Alternative Part Number

  • 74LVT245PW,118 --: Same LVT 3.3V octal bus transceiver function in a TSSOP package, pin-compatible with the SOIC-wide NSR footprint when board layout allows, from a major logic supplier.
  • MC74LVT245BDWR2G --: Direct LVT-family octal bus transceiver with 3-state outputs in a wide-body SOIC package, functionally equivalent and widely available.
  • 74LVT245BQ,115 --: LVT octal bus transceiver in a smaller DHVQFN package; suitable when a compact drop-in functional replacement is acceptable and layout can be adjusted.
