I noticed in the schematic that no pull up resistors are used with that chip, so they are internal. Chips with open collector outputs are not so easy to kill, but with internal pull-ups, a slip of the probe tip or contact with an uncovered probe ground ring may have been the cause of the damage, so probe with extreme caution.

I'm generally very careful and follow all safety precautions on anything I probe.:)

Thanks
