Description and Introduction

Octal Bus Transceiver With 3-State Outputs The SN74LV245ATDWR is an octal bus transceiver manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** Octal Bus Transceiver  
- **Number of Bits:** 8  
- **Voltage Supply Range:** 2 V to 5.5 V  
- **High-Level Output Current:** -12 mA  
- **Low-Level Output Current:** 12 mA  
- **Propagation Delay:** 7.5 ns (max) at 5 V  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package:** SOIC-20 (TSSOP)  

### **Descriptions:**  
- Non-inverting bidirectional voltage level translator  
- 3-state outputs for bus-oriented applications  
- Supports mixed-mode signal operation (5 V to 3.3 V)  
- Designed for asynchronous communication between data buses  

### **Features:**  
- **Wide Operating Voltage:** 2 V to 5.5 V  
- **Bidirectional Data Flow:** Controlled by DIR (Direction) pin

- **ESD Protection:** Exceeds 2000 V (HBM)  

This device is commonly used in level shifting, data buffering, and bus isolation applications.

Application Scenarios & Design Considerations

Octal Bus Transceiver With 3-State Outputs

Alternative Part Number

  • 74LVX245MTCX --: Octal bus transceiver with 3-state outputs in the LVX family, functionally equivalent to the LV245A and available in TSSOP, suitable as a direct logic-level replacement.
  • MC74LCX245DTR2G --: Low-voltage CMOS octal bus transceiver with 3-state outputs, comparable 2.3-3.6V operation and pinout, a common cross for LV245A designs.
  • 74LVC245APW --: Wide low-voltage octal bus transceiver in TSSOP with 3-state outputs, widely stocked and functionally interchangeable with the SN74LV245A in most bus-interface applications.
