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.^[5]
Motorola Semiconductor Components Group was spun into ON Semiconductor in 1999.^[6]
National Semiconductor was sold to Texas Instruments in 2011.^[7]

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.
