Other Parts Discussed in Thread: AM26C32
AM26C31とAM26C32で通信しているのですが、誤って15Ωの終端抵抗を取り付けてしまいました。
この場合、AM26C31、AM26C32、終端抵抗(1/2W)のいずれかが破損するのでしょうか?
(絶対最大定格には[入力または出力クランプ電流]20mAとあるので問題ないと思います。)

The clamp current has nothing to do with this.
The AM26C31's short-circuit current is guaranteed to be lower than its output current limit of 150 mA, so a 15 Ω termination will not damage it. I do not know if the actual output current is high enough to result in temperature problems.
The AM26C32 wants a differential input voltage of at least ±0.1 V, so the current through the termination resistor must be at least 7 mA. So this will work.
