APPLICATION INFORMATION
latch-up avoidance
Junction-isolated CMOS circuits have an inherent parasitic PNPN structure that can function as an SCR. Under
certain conditions, this SCR may be triggered into a low-impedance state, resulting in excessive supply current.
To avoid such conditions, no voltage greater than 0.3 V beyond the supply rails should be applied to any pin.
In general, the operational amplifier supplies should be applied simultaneously with, or before, application of
any input signals.
