†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.

ELECTRICAL CHARACTERISTICS

Electrical Characteristics: Unless otherwise noted, VDD = 5V for L/M versions, VDD = 3.3V for T/S versions,

VDD = 3V for R version, TA = –40°C to +125°C. Typical values are at TA = +25°C.

Note 1: Data in the Typical (“Typ.”) column is at 5V, +25

C, unless otherwise stated.

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

3: TC127XA refers to the TC1270A, TC1270AN or TC1271A device.

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

5: Custom-ordered voltage trip point. Minimum order volume requirement.

6: 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.
