Part Number: SN65HVD82

Dear:

SN65HVD82 datasheet CL "differential load capacitance 50pf" the mean is load capacitance when receiving ，right or not？

if I want to monitor muti-channels RS-485 load,  how to design the topology, any referred  design files to share me ?

    "Load" means something connected to the output. If you never transmit anything, you do not need to care about CL.

    To monitor a bus, connect the receiver directly to the two bus lines. To prevent reflections, the length of the stub from the bus to the chip should be as small as possible. (A RS-485 bus needs termination only at both ends.)
