Handling Procedure
Stresses above these listed maximum ratings may cause
permanent damage to the device. Exposure beyond specified
electrical characteristics may affect device reliability
Electrical parameters and functionality are not guaranteed
when the circuit is exposed to light.
This device has built-in protection against high static
voltages or electric fields; however, anti-static
precautions should be taken as for any other CMOS
component. Unless otherwise specified, proper
operation can only occur when all terminal voltages are
kept within the supply voltage range.
