I don't use 4 bit latches. No problem for me
:)
Other than the 4 bit adder 7486 I can't think of any common
chips with middle supply pins.
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.
(For me, the 7473 always seemed to stand out as the oddball pinout as the chip
was so common.)
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
remember?
The 74L86 quad XOR pinout differs from that of 7486, also 'L85/'85,
'L93/'93, 'L95/'95.
