I know, I know, this has been discussed on many a thread, and I did peruse a few a few minutes earlier, but didn't quite find the answer I was after, especially looking at the original version of the circuit I'm working on.
It seems the rules of thumb are that unused inputs on TTL gates should be pulled up... applicable to buffer ICs as well?
One circuit I'm working on replicating uses only half a 74LS241. The unused half has BOTH the inputs AND outputs left floating (pins 3-5-7-9-11-13-15-17), with the control line (19) pulled up to 5V through a 1K resistor.
Should I go back and modify the circuit to ground pins 11-13-15-17? (the original circuit was developed and produced around 1982)
