Notes
  • Pins for lit segments are high. The 4511 can directly drive a common cathode LED display.
  • Display is blanked for inputs greater than 9.

Note
Data is maintained by an independent source and accuracy is not guaranteed. Check with the manufacturer's datasheet for up-to-date information.
