; 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: RCA --> (Harris --> Intersil) --> Renesas -- Intersil was sold to Renesas Electronics in 2017.{{cite web |title=Renesas and Intersil Announce Final Regulatory Approval for Renesas' Acquisition of Intersil |url=https://www.renesas.com/us/en/about/press-center/news/2017/news20170222.html |website=Renesas Electronics |archive-url=https://web.archive.org/web/20200613181551/https://www.renesas.com/us/en/about/press-center/news/2017/news20170222.html |archive-date=June 13, 2020 |date=February 22, 2017 |url-status=live}}

; 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.
