So I'm monkeying around with another part of a schematic where it used two sets of NAND gates - a standard 74LS00 and the open-collector version, the 74LS03.
After a bit of feature cleanup, I have three unused 74LS03 gates and one unused 74LS00 gate, so I've a mind to keep the 74LS00 if I can.
The one remaining 74LS03 gate fed a gated clock signal to the NVRAM chips, but it now goes off-board and passes through a buffer on another board to serve as the master clock for that board.
Also, that 74LS03 gate currently has a pull-up resistor on it.
As I understand it, the main reason for using open-collector TTL is for interfacing with non-TTL loads, right?
Therefore, if running straight TTL all the way through now, there's no longer any reason to keep the remaining '03 gate, and I can just swap for the one unused '00 gate and then drop the '03 completely, right? Would I need to keep the pull-up if I swap that gate to use the '00?
