5.0 OPERATIONAL CHARACTERISTICS
5.1 Absolute Maximum Ratings*
Storage Temperature (T
S
)...................................................................................................................... –55°C to +150°C
Supply Referenced to GND ...................................................................................................................... –0.5V to +4.0V
All Pins ...................................................................................................................................................... –0.5V to +4.0V
*Exceeding the absolute maximum rating may damage the device. Stresses greater than the absolute maximum rating
may cause permanent damage to the device. Operation of the device at these or any other conditions above those spec-
ified in the operating sections of this specification is not implied. Maximum conditions for extended periods may affect
reliability.
