* Pb-free PDIPs can be used for through-hole wave solder
processing only. They are not intended for use in Reflow solder
processing applications.
CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product
reliability and result in failures not covered by warranty.
NOTES:
4. Due to the SCR structure inherent in the CMOS process used to fabricate these devices, connecting any terminal to a voltage greater than V+ +0.3V
or less than V- -0.3V 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 supply systems, the supply of the ICM7555 and
ICM7556 must be turned on first.
