*Static-sensitive device. Unused devices must be stored in conductive
material. Protect devices from static discharge and static fields. Stresses
above those listed under Absolute Maximum Ratings may cause perma-
nent 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 operational sections of the specifications is not implied.
ELECTRICAL CHARACTERISTICS: Unless otherwise stated, these specifications apply for – 40°C < TA <
+85°C for the TC25C25Exx; and 0°C <TA < +70°C for the TC35C25Cxx;
VIN and VDD = 16V; RT = 3.7kΩ; CT = 1000pF; RD = 760Ω.
