Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage (V_CC) is within the range of 2.25V to 5.5V.
   • Use a stable power source to avoid voltage fluctuations that can affect performance.

2. Temperature Considerations:

   • The operating temperature range is from -40°C to 85°C. Ensure the device is used within this range to maintain reliability.
   • Store the device in temperatures between -65°C and 150°C.

3. Input Signals:

   • The differential input voltage (V_IDIFF) should not exceed ±7V.
   • The common-mode input voltage (V_ICM) must be within the range of -0.3V to V_CC + 0.3V.

4. Output Signals:

   • The output voltage (V_OH) when high should be between V_CC - 0.4V and V_CC - 0.1V.
   • The output voltage (V_OL) when low should be between 0.1V and 0.4V.

5. Data Rate:

   • The device supports data rates up to 20 Mbps. Ensure the system clock and data signals are synchronized to achieve optimal performance.

6. Propagation Delay and Skew:

   • The typical propagation delay (t_PD) is 4.5 ns.
   • The skew (t_SK) between outputs is typically 0.5 ns.

7. Output Current:

   • The maximum output current (sink and source) is 16 mA. Ensure the load does not exceed this limit to prevent damage to the device.

8. Capacitance:

   • The input capacitance (C_IN) and output capacitance (C_OUT) are both 10 pF. Consider these values when designing the circuit to avoid signal degradation.

9. Handling and Storage:

   • Handle the device with care to avoid static discharge, which can damage the internal components.
   • Store the device in a dry environment to prevent moisture-related issues.
