- **Features:** Partial Power Down (Ioff), Bus-Hold, Over-Voltage Tolerant Inputs  

### **Descriptions:**  
The **SN74LVCHR16245ALR** is a 16-bit bus transceiver designed for 1.65V to 3.6V VCC operation. It features non-inverting 3-state outputs and is designed for asynchronous communication between data buses. The device supports partial power-down mode (Ioff) and has over-voltage-tolerant inputs, making it suitable for mixed-voltage applications.  

### **Features:**  
- **Bus-Hold Data Inputs:** Eliminates the need for external pull-up/pull-down resistors.  
- **Over-Voltage Tolerant Inputs:** Allows voltage levels up to 5.5V on inputs when VCC is 0V.  
- **Partial Power-Down (Ioff):** Supports live insertion.  
- **3-State Outputs:** Allows multiple devices to share a common bus.  
- **Balanced Propagation Delays:** Ensures minimal skew.  
- **ESD Protection:** Exceeds JESD 22 (2000V Human Body Model).

Application Scenarios & Design Considerations

16-Bit Bus Transceiver With 3-State Outputs

Alternative Part Number

  • 74LVC16245ADGG --: 16-bit bus transceiver with 3-state outputs, same LVC family logic and pin function, widely available alternative to the LVC16245A.
  • 74LVCH16245APVG --: 16-bit bus transceiver with bus-hold inputs, functionally equivalent to the LVCHR16245A with similar 3.3V operation.
  • 74LVC16245A --: Standard 16-bit bus transceiver in LVC logic, drop-in functional replacement for the 16245A function with 3-state outputs.
  • 74LVC16245APAG --: 16-bit bus transceiver with 3-state outputs in the same LVC logic family, functionally equivalent to the LVCHR16245A and available in TSSOP.
  • MC74LCX16245DTG --: 16-bit dual 8-bit transceiver with 3-state outputs, low-voltage CMOS logic, pin-compatible function and widely stocked alternative.
  • 74LVT16245BDGG --: 16-bit bus transceiver with 3-state outputs in LVT family, similar 3.3V operation and bus-hold behavior, suitable drop-in functional replacement.
