Instructions for Use
Power Supply:
- Ensure the supply voltage (VCC) is within the specified range of 4.75V to 5.25V.
- Connect a decoupling capacitor (typically 0.1μF) close to the power pins to stabilize the supply.
Temperature Considerations:
- The device is designed to operate within the temperature range of -40°C to 125°C.
- Store the device in an environment where the temperature does not exceed -65°C to 150°C.
Differential Output:
- The differential output voltage (VOD) should be between 0.9V and 1.1V under normal operating conditions.
- The common-mode output voltage (VOC) should be between 2.0V and 3.0V.
Input Signals:
- Ensure that the input signals meet the threshold voltages:
- High-level input voltage (VIH) should be between 2.0V and 3.0V.
- Low-level input voltage (VIL) should be between 0.8V and 2.0V.
- Ensure that the input signals meet the threshold voltages:
Timing Parameters:
- The propagation delay (tPLH and tPHL) should be around 15ns.
- The skew (tSKW) should be no more than 2ns.
- The rise time (tR) and fall time (tF) should be around 20ns.
Output Current:
- The device can source or sink up to ±100mA of current at the output.
Layout and PCB Design:
- Use short and direct traces for signal lines to minimize noise and ensure reliable operation.
- Place the device away from high-frequency noise sources and heat-generating components.
Handling:
- Handle the device with care to avoid static damage. Use appropriate ESD protection measures.
- Follow the recommended soldering profile to ensure proper bonding without damaging the device.
By following these parameters and instructions, you can ensure optimal performance and reliability of the SN65HVD05DR.
