Nice ! Now that would be more useful if they were sorted by number :-D

https://en.wikipedia.org/wiki/List_of_7400_series_integrated_circuits says : 7440 dual NAND4

  Are you sure? yes | no

Aha! but it's a 744040, right?

  Are you sure? yes | no

From the wikipedia page : 

Some manufacturers released some 4000
equivalent CMOS circuits with a 74 prefix, for example the 74HC4066 was
a replacement for the 4066 with slightly different electrical
characteristics (different power supply voltage ratings, higher
frequency capabilities, lower "on" resistances in analog switches,
etc.). See list of 4000 series integrated circuits.

Conversely, the 4000 series has "borrowed" from the 7400 series - such as the CD40193 and CD40161 being pin-for-pin functional replacements for 74C193 and 74C161. There is some reference to double-borrowings, such as 74193 -> 40193 -> 74HC40193.[1]
