Turning on and off ADM3251E causes audible click

Hi,

 

We are currently working with an MSP430 communicating to an ADM3251E RS232 interface. In order to save power the 5V supply on the ADM3251E is turned off after every RS232 transmission which runs once a second. We are now hearing an audible click from the chip.

 

Is the click normal? Will it have any effect on the life of the chip?

 

Thanks
