You shouldn't if it is TTL compatible, it depends on what you are driving in to?
Try them on their own with a 2k PU resistor if necessary to test.

plutp-P board encoder inputs I have AMT102 encoders .They output max 5mA current TTL signals and nothing counts when i rotate encoder. Do i need to give pull up resistors for inputs?
Any shematics for input signals will be wellcome
