Table notes
  • For the "0" to "F" columns,
  • each 4-bit input is shown as its 7-segment decoded output.
  • For the "Output" column,
  • Active-High means a high occurs when a segment is on, where as Active-Low means a low occurs when a segment is on.
  • PP means Push-Pull output driver, OC means Open-Collector output driver, OE means Open-Emitter output driver, CC means Constant Current output driver.
  • For the "Manufacturer" column,
TODO
  • Finish manufacturer historical list.
  • Maybe describe outputs. Output for 0 / 2 / 3 / 4 / 5 / 8 are the same for all ICs. MC14558B has a different output for 1. TC5022 has a different output for 7. Output for 6 & 9 vary across the ICs.
