Electrical Characteristics

Absolute Maximum Ratings

DC Parameters

TA = -40°C to +85°C; VSS = 0V; VCC = 3.3V ± 10%; F = 0 to 40 MHz

Ambient Temperature Under Bias:

I = industrial ........................................................-40°C to 85°C

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

Voltage on VCC from VSS......................................-0.5V to + 6V

Voltage on Any Pin from VSS .....................-0.5V to VCC + 0.2V

Note:

Stresses at or 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 these or any other condi-

tions above those indicated in the operational

sections of this specification is not implied. Exposure

to absolute maximum rating conditions may affect

device reliability.
