† Notice: Stresses above those listed under "Absolute

Maximum Ratings" may cause permanent damage to

the device. This is a stress ratings only and functional

operation of the device at those or any other conditions

above those indicated in the operational listing of this

specifications is not implied. Exposure to Absolute

Maximum Rating conditions for extended periods may

affect device reliability.

Note 1:

Data in the Typical (“Typ”) column is at 5V, +25

°C, unless otherwise stated.

RST output for TC1270A, and TC1270AN, RST output for TC1271A.

TC127XA refers to either the TC1270A, TC1270AN or TC1271A device.

Hysteresis is within the VTRIP(MIN) to VTRIP(MAX) window.

Custom ordered Voltage Trip Point. Minimum order volume requirement.

This specification allows this device to be used in PIC® microcontroller applications that require the

In-Circuit Serial Programming™ (ICSP™) feature (see device-specific programming specifications for

voltage requirements). The total time that the RST pin can be above the maximum device operational

voltage (5.5V) is 100s. Current into the RST pin should be limited to 2 mA. It is recommended that the

device operational temperature be maintained between 0°C to +70°C (+25°C preferred). For additional

information, refer to Figure 2-41.
