Instructions for Use

1. Power Supply:

   • Ensure the supply voltage (VCC) is within the specified range of 4.75V to 5.25V.
   • Connect a decoupling capacitor (0.1渭F) close to the VCC and GND pins to stabilize the power supply.

2. Input Signals:

   • The differential input voltage (VID) should not exceed 2V.
   • The common-mode input voltage (VICR) must be within the range of 0V to 5V.

3. Output Configuration:

   • The output voltage high (VOH) should be at least 2.4V when sourcing 4mA.
   • The output voltage low (VOL) should be no more than 0.4V when sinking 8mA.

4. Timing Considerations:

   • The propagation delay (tpd) from input to output is typically 7ns but can range from 5ns to 10ns.
   • Ensure that the skew (tskew) between channels does not exceed 1ns to maintain signal integrity.

5. Temperature Range:

   • The device operates reliably within the temperature range of -40掳C to 85掳C.
   • Store the device in temperatures ranging from -65掳C to 150掳C.

6. Handling Precautions:

   • Handle the device with care to avoid static discharge, which can damage the internal circuits.
   • Follow proper soldering techniques to ensure reliable connections and prevent thermal damage.

7. Application Notes:

   • For optimal performance, use the device in applications requiring high-speed differential signaling.
   • Refer to the datasheet for detailed application circuits and layout guidelines.
