Quad LVDS Receiver, DS90lV047A - 1. Can it be damaged if it is not powered up and is driven by an LVDS driver chip; 2. Is there a pin-to-pin "latch-up immune" version of this?

Hi,

I think I damaged the chip when the chip on the board was not powered up an was driven by an LVDS driver.  Now there is a 3.3 volt to ground short on the board.

    Hi Ken,

    This sounds more like an ESD or Electrical overstress event.  The DS90LV047A is an LVDS driver.  do you have multiple LVDS drivers connected together. the LVDS outputs of the DS90LV047A are designed to handle voltages up to 3.6V when VCC = GND = 0V.

    Regards,
