6.1.4 Latchup

CMOS devices tend to be susceptible to latchup due to internal parasitic silicon controlled rectifier (SCR) effects. The input and output (I/O) pins look similar to the gate of the SCR. There is a minimum current required to trigger the SCR gate lead. The LMC606x are designed to withstand 100mA surge current on the I/O pins. Use a resistive method to isolate any capacitance from supplying excess current to the I/O pins. In addition, like a SCR, there is a minimum holding current for any latchup mode. Limiting current to the supply pins also inhibits latchup susceptibility.
