Microchip Technology 

TC1040

1.0 ELECTRICAL

CHARACTERISTICS

ABSOLUTE MAXIMUM RATINGS*

Supply Voltage ......................................................6.0V

Voltage on Any Pin .......... (VSS – 0.3V) to (VDD + 0.3V)

Junction Temperature....................................... +150°C

Operating Temperature Range............. -40°C to +85°C

Storage Temperature Range .............. -55°C to +150°C

*Stresses above those listed under "Absolute Maximum

Ratings" may cause permanent damage to the device. These

are stress ratings only and functional operation of the device

at these or any other conditions above those indicated in the

operation sections of the specifications is not implied.

Exposure to Absolute Maximum Rating conditions for

extended periods may affect device reliability.

TC1040 ELECTRICAL SPECIFICATIONS

Electrical Characteristics: Typical values apply at 25°C and VDD = 3.0V. Minimum and maximum values apply for TA = -40° to

+85°C and VDD = 1.8V to 5.5V, unless otherwise specified.
