Input voltage at bus terminal of these RS485 transceivers LTC2862H

Question

Hi. 
 What is the input voltage at bus terminal of LTC2862H? We have our own special application on RS485 transceiver like below, 
 RS485 Master : connect B to GND and connect A to 12-16V. 
 RS485 Slave : one(can be A or B) to GND minus one diode and one(can be A or B) to 12-16V (possible 24V) minus one diode. 
 
 Will the LTC2862H be able to handle LTC2862H with the application above?

Hi Nancy, 
 Thank you for the detailed description, this is very helpful. 
 I have confirmed with our design team that there is no problem with a differential A-B voltage of +16V or -16V while at a common mode voltage of 8V for regular operation. Your use case is within the normal operating bounds of the LTC2862 
 Any voltages on the A or B pins within the +/-25V common mode range can be reliably placed on the A and B pins for the lifetime of the device.

Hi Nancy, 
 This second condition is also no problem, in reality for reliable long term/lifetime operation, there is a very large margin to the stated +/-25V common mode range
