Instructions for Using the MAX487ECPA

1. Supply Voltage (V_CC):

   • Ensure the supply voltage is within the range of 4.75 V to 5.25 V.
   • Connect the V_CC pin to the positive power supply and GND to the ground.

2. Input and Output Capacitance:

   • The input and output capacitance should be around 10 pF. Use appropriate capacitors if necessary to match this value.

3. Driver Output Levels:

   • Ensure that the driver output high level (VOH) is at least 2.4 V when the output current is -4 mA.
   • Ensure that the driver output low level (VOL) is no more than 0.4 V when the output current is 4 mA.

4. Driver Timing Parameters:

   • The rise time (t_R) and fall time (t_F) should be around 250 ns under typical conditions.
   • The propagation delay (t_PD) should be around 350 ns.
   • The skew (t_SKW) between the rising and falling edges should be around 50 ns.

5. Receiver Input Levels:

   • The receiver input high level (VIH) should be at least 2.0 V.
   • The receiver input low level (VIL) should be no more than 0.8 V.

6. Receiver Output Levels:

   • Ensure that the receiver output high level (VOH) is at least 2.4 V when the output current is -400 μA.
   • Ensure that the receiver output low level (VOL) is no more than 0.4 V when the output current is 400 μA.

7. Receiver Propagation Delay:

   • The propagation delay (t_PD) for the receiver should be around 350 ns.

8. Power Consumption:

   • The power consumption (I_CC) should be around 250 μA under no load conditions.

9. Layout Considerations:

   • Keep the traces short and direct to minimize signal degradation.
   • Use decoupling capacitors close to the V_CC and GND pins to reduce noise.

10. Operating Temperature:

    • The device is designed to operate over a temperature range of -40°C to +85°C.

By following these parameters and instructions, you can ensure optimal performance and reliability of the MAX487ECPA in your application.
