I have a bunch of 74LS383 (TTL octal transparent latch with three-state outputs) and MM74C83N (CMOS 4-bit binary full adder) that I would like to connect together. I need to connect the output of the 74383 to the input of the 7483 as well as vice versa. The problem is the voltage level.
If I understand correctly, there is no problem connecting CMOS outputs to TTL inputs if the fan-out is OK, but connecting TTL outputs to CMOS inputs may give issues with the voltage levels.
Could I use a pull-up to workaround this issue? What would be a good value?
