The only reason I can think of is that back in those days when the chip was first made some company ordered the chips with this pinout to fit in their deisgn better, and later on the manufacturer made the same chip but this time with connections made in the standard way.

74LS83 4-bit Binary Full Adder IC | Tinkbox

Be careful though, if an input is not connected, it may appear to have low voltage on it when measured but still be ‘seen’ from insde the IC as being high, you actually have to draw current from the pin to be sure it really is logic low.

See the picture of the 744ls83 which is attached.


Don’t forget that in a real computational circuit the inputs would actively be jc by other devices, here you are trying to simulate them with resistors and switches. Jan 19, 5. PNP transistor not working 2. Maybe you could try comparing the datasheets.
