RST output for TC1270A, and TC1270AN, RST output for TC1271A.
TC127XA refers to the TC1270A, TC1270AN, or TC1271A device.
Hysteresis is within the V
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

† Notice: Stresses above those listed under “Absolute
Maximum Ratings” may cause permanent damage to a
device. The absolute maximum values are merely
stress ratings – functional operation of a device at
those, or any other conditions above those indicated in
the operational listing of these specifications, is not
implied. Exposure to absolute maximum rating
conditions for extended periods may affect device
reliability.
