CMOS latchup is a phenomenon in integrated circuits where parasitic thyristors are inadvertently triggered, causing a short circuit. CMOS latchup occurs when a parasitic structure in the CMOS device acts as a thyristor, leading to a low-impedance path between the power supply rails. It can result in excessive current flow, potentially damaging the device. Preventive measures include layout techniques, guard rings, and proper power supply decoupling. Example: In a CMOS IC, if the voltage at the input pin exceeds the power supply voltage, latchup may occur.
