Specification on Output
Pins
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 either the TC1270A, TC1270AN or TC1271A device.
4:
Hysteresis is within the V
TRIP(MIN)
to V
TRIP(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
