am26ls32 terminating resistor value issue

[raman00084]

should i must use any terminating resistor in the input of am26ls32. i am having a servo drive in that the encoder outputs are as follows OA+,OA-,OB+,OB- i think differential can i use the above ic to take a single line out such as A and B alone with respect to gnd. my doubt is terminating resistor is needed? if so what is the value.

If you are using twisted pair, a 120 ohm resistor would work. But that's without you telling us anything about your encoder outputs; what are they +/- 1,000,000 Volts?

And why would you use a differential receiver and connect it to a device with differential outputs and then NOT use the differential outputs?
