11.1 Layout Guidelines

Following common printed-circuit board layout guidelines are recommended to ensure reliability of the device, which follows:

  • Use bypass capacitors on the power supply pins and place them as close to the device as possible. A 0.1 µF capacitor is recommended, but transient performance can be improved by having both 1 µF and 0.1 µF capacitors in parallel as bypass capacitors.
  • The high drive capability of this device creates fast edges into light loads; so routing and load conditions should be considered to prevent ringing.
