*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.
TC1270/TC1271 ELECTRICAL SPECIFICATIONS
Electrical Characteristics: VCC = 5V for L/M versions, VCC = 3.3V for T/S versions, VCC = 3V for R version, VCC =2.0V for F
version. TA = -40°C to +85°C unless otherwise noted. Typical values are at TA =+25°C.(Note 1).
