Note 1: Due to the SCR structure Inherent tn the CMOS process used to tabncate these devnces. connecting any terminal to a voltage greater than
( +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 devtce before Its power supply IS established In multiple systems. the supply of the
ICM7555/6 must be turned on first,
Note 2: Junction temperatures should not exceed 135°C and the power dssoahon must be Itmlted to 20mW at IPS C Below 125''C powet dissipation
may be Increased to 300mW at 25cC Deratlng factor IS approximately 3mwwc (7556) Or 2mWil (7555)
Note 3: The supply current value IS essentially independent of the TRIGGER, THRESHOLD and RESET voltages
Note 4: Parameter IS not 100% tested Majority of all units meet this specfcation
