Follow these general guidelines when
designing the power supply:
- The power supply should be
designed to provide the operating conditions outlined in the Recommended
Operating Conditions for DC voltage, AC noise, and start-up ramp
time.
- The SN75LVPE3410 does not require any
special power supply filtering, such as ferrite beads, provided that the
recommended operating conditions are met. Only standard supply decoupling is
required. Typical supply decoupling consists of a 0.1 µF capacitor per VDD
pin, one 1.0 µF bulk capacitor per device, and one 10 µF bulk capacitor per
power bus that delivers power to one or more SN75LVPE3410 devices. The local
decoupling (0.1 µF) capacitors must be connected as close to the VDD pins as
possible and with minimal path to the SN75LVPE3410 ground pad.
