**Part Number:**THVD1400

Dear Expert ,

Good day!

Our customer want to use THVD1400 to make a 485 network system. There are more than 200 loads, and the transmission distance is about 28 meters. The load is evenly distributed. The resistance of the number line is 0.17 ohm/meter. The resistance of the power cord is 0.05 ohm/meter. The maximum power of each load is 0.12w. Now we want to know. Can the 485 chip work normally in this kind of network? What is the sink voltage that THVD1400 can withstand in normal operation? (only one driver)

BR,

Leon.liu
