ELECTRICAL CHARACTERISTICS

Absolute Maximum Ratings (?)

V CC .............................................................................................................................................................................6.5V

All inputs and outputs w.r.t. V SS ......................................................................................................... -0.6V to V CC +1.0V

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

Ambient temperature under bias ...............................................................................................................-40°C to 125°C

? NOTICE : Stresses above those listed under “Absolute 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 operational listings of this specification is not implied. Exposure to maximum rating conditions for an

extended period of time may affect device reliability.
