### **Descriptions:**  
The SN74LVT16543DGGR is a 16-bit bus transceiver designed for low-voltage (2.7V to 3.6V) applications. It features non-inverting 3-state outputs and bidirectional data flow controlled by output enable (OE) and direction (DIR) inputs.  

### **Features:**  
- **Bidirectional Data Flow:** Controlled by DIR input.  
- **3-State Outputs:** Allows multiple devices to share a common bus.  
- **LVT Technology:** Combines high-speed performance with low power consumption.  
- **Bus-Hold on Data Inputs:** Eliminates the need for external pull-up/pull-down resistors.  
- **ESD Protection:** Exceeds 2000V per JESD 22.  
- **Wide Operating Voltage Range:** 2.7V to 3.6V.  
- **High-Speed Operation:** Optimized for 3.3V systems.  
- **Power-Up High-Impedance State:** Prevents bus contention during power-up.  

This device is commonly used in data communication systems, networking equipment, and other applications requiring bidirectional data transfer.

Application Scenarios & Design Considerations

3.3-V ABT 16-Bit Registered Transceivers With 3-State Outputs

Alternative Part Number

  • 74LVT16543ADGG --: Same 16-bit registered transceiver function in a TSSOP package, pin-compatible with the TI device and widely available.
  • 74LVT16543ADL --: Equivalent LVT 16-bit transceiver with similar speed and drive, offered in SSOP for drop-in board compatibility.
  • 74ABT16543DGGR --: ABT-family 16-bit registered transceiver with comparable function and TSSOP footprint, usable when slight speed differences are acceptable.
  • 74LVT16543DGG --: Same 16-bit registered transceiver function in the same TSSOP-56 package, pin-compatible with the LVT family and a direct functional drop-in.
  • 74LVTH16543DGG --: LVTH variant of the same 16-bit transceiver with bus-hold inputs, same pinout and package, suitable when bus-hold is acceptable or beneficial.
  • 74LVT16543MTD --: Equivalent LVT 16-bit registered transceiver in TSSOP-56, same logic function and pinout, usable as a second-source alternative.
