### **Descriptions:**  
The SN74LVC245APW is an octal bus transceiver designed for asynchronous communication between data buses. It features direction control (DIR) and output enable (OE) inputs to manage data flow.  

### **Features:**  
- **Wide Operating Voltage:** Supports 1.65 V to 3.6 V  
- **Bidirectional Data Flow:** Controlled by DIR input  
- **3-State Outputs:** Allows bus isolation when OE is high  
- **Low Power Consumption:** ICC typically 10 µA  
- **ESD Protection:** Exceeds 2000 V (HBM) and 1000 V (CDM)  
- **Latch-Up Performance:** Exceeds 250 mA per JESD 17  

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

Application Scenarios & Design Considerations

Octal Bus Transceiver With 3-State Outputs

Alternative Part Number

  • 74LVC245APW,118 --: Pin-compatible octal bus transceiver in the same TSSOP-20 package with equivalent 3.3V LVC logic levels and drive strength.
  • MC74LCX245DTG --: Functionally equivalent octal bus transceiver with 5V-tolerant inputs, available in TSSOP-20, suitable drop-in replacement for level-shifting bus applications.
  • 74LVC245APW-Q100,118 --: Automotive-qualified octal bus transceiver in TSSOP-20 with matching LVC family characteristics and pinout for higher-reliability designs.
  • 74LVC245APW --: Same octal bus transceiver function and LVC family with identical PW (TSSOP-20) package, widely available as a direct second source.
  • 74LVC245APW-Q100 --: Automotive-qualified LVC octal transceiver in TSSOP-20, same logic function and pinout for drop-in use where AEC-Q100 parts are acceptable.
