Typical Application Information
General application guidelines and hints for differential driv-
ers and receivers may be found in the following application
notes:
AN-214, AN-457, AN-805, AN-847, AN-903, AN-912, AN-
916.
Power Decoupling Recommendations:
Bypass caps must be used on power pins. High frequency
ceramic (surface mount is recommended) 0.1 µF in parallel
with 0.01 µF at the power supply pin. A 10 µF or greater solid
tantalum or electrolytic should be connected at the power
entry point on the printed circuit board.
