IC ADM2481 with ADM2483

Question

As due to Chip Shortage adm2481 IC are selling Five times of its cost. We can get adm2483 at good price. 
 Can i replace adm2481 with adm2483 with just Putting PV Pin High State? 
 
 With this we will not have to change much hardware. Please Guide

Hi, 
 ADM2481 is intended to simplify the design by not requiring the PV input. If PV on ADM2483 (note this is pin 7, GND1 on ADM2481) is tied to VDD1, then ADM2483 will operate similarly (RS-485 DC/AC specifications), but could have chatter on A and B at power-up/power-down if the ramp is slower (>100 us/V). If you expect slow power up/power down ramps then follow the ADM2483 datasheet recommendations (e.g. reset circuit on PV) or ensure the system can avoid disruption (e.g. at software/protocol level) due to A, B chatter. 
 Best regards,
