3.0V/3.3V Low Power Microprocessor Supervisory
Circuits
ABSOLUTE MAXIMUM RATINGS
These are stress ratings only and functional operation of
the device at these ratings or any other above those
indicated in the operation sections of the specifications
below is not implied. Exposure to absolute maximum
rating conditions for extended periods of time may affect
reliability.
V_CC .......................................................... -0.3V to 6.0V
All Other Inputs (Note 1) ................... -0.3V to (V_CC+0.3V)
Input Current
VCC .................................................................20mA
GND ................................................................20mA
Output Current (All outputs) ...............................20mA
ESD Rating (HBM - Human Body Model) .................... 2kV
Continuous Power Dissipation
SO (derate 5.88mW/°C above +70°C)...............471mW
Mini SO (derate 4.10mW/°C above +70°C) ........330mW

ELECTRICAL SPECIFICATIONS
Unless otherwise indicated, V_CC = 2.7V to 5.5V (SP70xR), V_CC = 3.15V to 5.5V (SP70xS), V_CC = 3.0V to 5.5V (SP70xT), T_A=
T_MIN to T_MAX, typical at 25°C.
