Description and Introduction

3.3-V ABT Octal Bus Transceivers With 3-State Outputs The SN74LVTH245APW is a 3.3V ABT octal bus transceiver manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Technology Family:** LVTH (Low-Voltage BiCMOS Technology)  
- **Supply Voltage Range:** 2.7V to 3.6V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Number of Channels:** 8 (Octal)  
- **Logic Type:** Transceiver, Non-Inverting  
- **Output Type:** 3-State  
- **Package Type:** TSSOP (PW)  
- **Package Pins:** 20  
- **High-Level Output Current:** -32 mA  
- **Low-Level Output Current:** 64 mA  
- **Propagation Delay Time:** 3.8 ns (max) at 3.3V  
- **I/O Compatibility:** 5V Tolerant Inputs  

### **Descriptions:**  
The SN74LVTH245APW is a bidirectional octal bus transceiver designed for asynchronous communication between data buses. It features 3-state outputs and is optimized for low-voltage (3.3V) operation while maintaining 5V input tolerance. It includes direction control (DIR) and output enable (OE) inputs for managing data flow.  

### **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-plugging applications  
- **ESD Protection:** Exceeds 2000V per JESD 22

Application Scenarios & Design Considerations

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

Alternative Part Number

  • 74LVT245PW --: Same LVT-family octal bus transceiver in TSSOP-20 with 3.3V operation and 5V-tolerant I/O, a direct functional equivalent from a different vendor.
  • MC74LVX245DT --: Octal bus transceiver in TSSOP-20 with similar low-voltage CMOS logic and 5V-tolerant inputs, suitable as a drop-in functional replacement.
  • 74LVC245APW --: Widely available octal bus transceiver in TSSOP-20 with 3.3V supply and 5V-tolerant inputs; slightly lower drive than LVT but pin-compatible for most designs.
  • MC74LVX245DTG --: Octal bus transceiver in the same LVX logic family with 3.3V operation and 5V-tolerant inputs, functionally equivalent to the SN74LVTH245A in a TSSOP package.
  • TC74LCX245FT --: Low-voltage CMOS octal bus transceiver with 3-state outputs, offering equivalent bidirectional bus driving in a comparable TSSOP-style package.
