Hi Experts,

Could you teach me status of GPIB bus port while power off and equivalent circuit.

What is the resistance value between the port and GND?

Mitsuda-san,

With power off, the resistance between port and GND could be as low as 60Ohm (2.5V/40mA). You can refer to the schematic on page 3 of the data sheet. If you want to check out TI's latest RS485, please go to this post.
