Vcc+ Vcc- short, Failure reason for TS393 6Z60

  1. I am using TS393 micropower dual CMOS Comparator for last 8-10 years, in my schematic. The PCB is heavily lacquered to protect against moisture damage.
  2. Today, in one working board, my team was changing TS393 associated resistor. After the change we noticed the Baord has short circuit in its power pins.
  3. Which was traced to Vcc+[pin8] Vcc- [pin 4] of the TS393.
  4. What could be the reason for such a absurd failure ?
  5. I checked the faulty TS393 chip, does not have any other pins of the six pins shorted with Vcc+ or Vcc-.
  6. Curious to know what all can lead to such internal shortage in TS393 power pins ?
