- Table notes
- For the "0" to "F" columns,
- each 4-bit input is shown as its 7-segment decoded output.
- 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.
