### Descriptions:  
The SN74ALVTHR16245GR is a 16-bit bus transceiver designed for low-voltage (1.65V to 3.6V) operation. It features non-inverting 3-state outputs and bidirectional data flow controlled by output-enable (OE) and direction-control (DIR) inputs.  

### Features:  
- **Wide Operating Voltage:** Supports 1.65V to 3.6V  
- **Bus-Hold on Data Inputs:** Eliminates need for external pull-up/pull-down resistors  
- **Partial Power-Down Protection:** Supports mixed-voltage applications  
- **High Drive Outputs:** ±12mA at 3.3V  
- **3-State Outputs:** Allows multiple devices to share a common bus  
- **ESD Protection:** Exceeds 2000V per JESD 22  
- **Low Power Consumption:** Optimized for battery-operated devices  
- **Bidirectional Data Flow:** Controlled by DIR input  

This device is commonly used in data communication, networking, and other digital systems requiring voltage-level translation and bus interfacing.

Application Scenarios & Design Considerations

2.5-V/3.3-V 16-Bit Bus Transceiver With 3-State Outputs

Alternative Part Number

  • 74ALVTHR16245GRE4 --: Same ALVTHR 16-bit transceiver family from TI with identical electrical specifications, offered in the same TSSOP package; the E4 suffix denotes lead-free/RoHS ordering variant.
  • 74ALVT16245DGG --: ALVT 16-bit bus transceiver with comparable 3.3V low-voltage performance and pin-compatible TSSOP footprint; a well-established second-source option when the HR bus-hold feature is not strictly required.
  • 74ALVC16245PA --: ALVC 16-bit transceiver providing similar 3.3V low-voltage translation and drive capability in a TSSOP package; suitable as a functional substitute where bus-hold is not needed.
  • 74ALVT16245DG --: ALVT 16-bit bus transceiver with similar 3.3V operation and pinout, a common cross-vendor substitute when the ALVTHR variant is unavailable.
  • 74ALVC16245DGG --: ALVC 16-bit transceiver in the same package style with comparable speed and 3.3V logic levels, suitable as a functional replacement with minor timing differences.
