Latchup
rent required to trigger the SCR gate lead. The LMC6061
and LMC6081 are designed to withstand 100 mA surge cur-
rent on the I/O pins. Some resistive method should be used
to isolate any capacitance from supplying excess current to
the I/O pins. In addition, like an SCR, there is a minimum
holding current for any latchup mode. Limiting current to the
supply pins will also inhibit latchup susceptibility.
