i paralleled 3 of the 8 pairs but the current requirements of the 2803 were pulling down the voltage output of the latch below ttl levels. none of the applications that i have seen show a setup where both the inputs and the outputs are paralleled but it has been mentioned. the motorola data sheet, for the darlington pairs, mentioned that each input required 25mA. one pin would push the limit of the latches ability to source the current. i was thinking of putting a npn in the path as a switch to source the current. would this be a good idea or am i wrong from the start?
