Requirement: Overdrive
The largest signal voltage permitted without causing latchup while the power is on shall be 0.4 V above the supply voltage (nominally 5 V). The SCA is not required to meet other functional requirements at this input level. The smallest signal voltage permitted shall be 0.4 V below analog ground. The SCA is not required to meet other functional requirements at this input level.
Justification:
Protection from transients.
