3.0V/3.3V Microprocessor Supervisory Circuits

_______________________________________________________________________________________

ELECTRICAL CHARACTERISTICS (continued)

(VCC = 3.17V to 5.5V for the MAX690T/MAX704T/MAX80_T, VCC = 3.02V to 5.5V for the MAX690S/MAX704S/MAX80_S, VCC = 2.72V to

5.5V for the MAX690R/MAX704R/MAX80_R; VBATT = 3.6V; TA = TMIN to TMAX; unless otherwise noted. Typical values are at TA = +25˚C.)
