APPLICATION INFORMATION

latch-up (continued)

The current path established if latch-up occurs is usually between the positive supply rail and ground and can

be triggered by surges on the supply lines and/or voltages on either the output or inputs that exceed the supply

voltage. Once latch-up occurs, the current flow is limited only by the impedance of the power supply and the

forward resistance of the parasitic thyristor and usually results in the destruction of the device. The chance of

latch-up occurring increases with increasing temperature and supply voltages.
