Description and Introduction

Octal Bus Transceivers With 3-State Outputs The SN74LV245A is an octal bus transceiver manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Technology Family:** LV (Low-Voltage)  
- **Supply Voltage Range:** 2 V to 5.5 V  
- **Operating Temperature Range:** -40°C to 85°C  
- **Number of Channels:** 8 (Octal)  
- **Logic Type:** Bidirectional Transceiver  
- **Output Type:** 3-State  
- **Propagation Delay (Max):** 10.5 ns at 5 V  
- **Input/Output Compatibility:** TTL, CMOS  
- **Package Options:** SOIC, TSSOP, PDIP  

### **Descriptions:**  
The SN74LV245A is an octal bus transceiver designed for asynchronous communication between data buses. It features bidirectional data flow controlled by the direction (DIR) input and an output enable (OE) input to disable the outputs. It operates at low voltage while maintaining compatibility with TTL and CMOS logic levels.  

### **Features:**  
- **Wide Operating Voltage:** Supports 2 V to 5.5 V  
- **Bidirectional Data Flow:** Controlled by DIR pin  
- **3-State Outputs:** Allows bus isolation when disabled  
- **High Drive Outputs:** ±24 mA at 3.3 V  
- **Low Power Consumption:** ICC typically 20 µA  
- **ESD Protection:** Exceeds 2000 V (HBM)  

This information is strictly based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

Octal Bus Transceivers With 3-State Outputs

Alternative Part Number

  • MC74VHC245ADWR2G --: Octal bus transceiver with 3-state outputs in the same VHC/VHC-family logic class, pin-compatible SOIC-20 wide body, widely available and cost-effective direct functional replacement.
  • 74LVC245APW --: Octal bus transceiver with 3-state outputs, 3.3V LVC family with 5V-tolerant inputs, pin-compatible TSSOP-20, good drop-in for level-shifting bus applications.
  • SN74HCT245N --: Same manufacturer octal bus transceiver with 3-state outputs in HCT family, pin-compatible DIP-20, useful when a through-hole or 5V TTL-compatible interface is required.
