If your designs are old enough, there are a bunch. 7441 = BCD to 7-
segment gas tube driver. 7492, 7493 = 4 bit counter, 7473 = dual JK
FF, 7476 = dual JK FF and almost all of the other "non-7400" TTL
stuff, such as the MC400, 500, 2000, etc. series.
It seems to me that there was one oddball case of a 74L series chip
having a different pinout that the 74 "vanilla" flavor. Anyone
