ELECTRICAL

CHARACTERISTICS

*Notice: Stresses above those listed under “Maximum

Ratings” may cause permanent damage to the device. This is

a stress rating only and functional operation of the device at

those or any other conditions above those indicated in the

Absolute Maximum Ratings*

V DD1,2 .............................................................................6.5V

operational listings of this specification is not implied.

Exposure to maximum rating conditions for extended periods

may affect device reliability.

All Inputs and Outputs w.r.t. V SS ..............-0.3 to (V DD + 0.3)V

Maximum Junction Temperature, T J ............ Internally Limited

Storage temperature .....................................-65°C to +150°C

ESD protection on all pins:

Human Body Model (1.5kW in Series with 100pF) .... ≥ 4 kV

Machine Model (200pF, No Series Resistance) ..........400V

DC CHARACTERISTICS

Electrical Specifications: Unless otherwise indicated, all limits apply for V DD = [V REG (Typ) + 0.3V] to 5.5V,

T A = -40°C to 85°C. Typical values are at +25°C, V DD = [V REG (Typ) + 1.0V]
