Limiting values
[1]
Due to the SCR structure inherent in the CMOS process used to fabricate these devices, connecting any terminal to a voltage greater
than VDD + 0.3 V or less than GND − 0.3 V may cause destructive latch-up. For this reason it is recommended that no inputs from
external sources not operating from the same power supply be applied to the device before its power supply is established. In multiple
systems, the supply of the ICM7555 must be turned on first.
