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 indi-

cated in the operation sections of the specifications is not

implied. Exposure to Absolute Maximum Rating conditions

for extended periods my affect device reliability.

TC1043 ELECTRICAL SPECIFICATIONS

Electrical Characteristics: Typical values apply at 25°C and VDD = 3V. Minimum and maximum values apply for TA =-40° to

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