    Hi, I need to switch between 28V and 12V supplies controlled by a LVTTL signal. I am using ADG5234 device. But the IC seems to blow up as soon as it is powered. VSS pin is grounded in the board. Is there anything which I am doing wrong or needs changes?VDD to the device is 28V.

        Hi, I have attached the schematic where I have used ADG5234 device. 
        
 
        I am using the LFCSP_WQ package.
        
 
        Pin 1 is taken as an output pin which is connected to the gate of IRF5803 MOSFET.
        
 
        Pin 2 is connected to 12V supply.
        
 
        Pin 3,4 and 18 are connected to GND.
        
 
        Pin 19 is connected to LVTTL pulse.
        
 
        Pin 20 is connected to 28V supply line.
        
 
        Application of this circuit is to switch between 28V and 12V based on the LVTTL control.
