* 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: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the
device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
NOTES:
1. 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 latchup. 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.

θ
JA is measured with the component mounted on a low effective thermal conductivity test board in free air. See Tech Brief 379 for details.
