ELECTRICAL CHARACTERISTICS (continued)
(VCC = +3.0V to +5.5V, TA = -40°C to +85°C, unless otherwise noted. Typical values are at VCC = +3.3V, TA = +25°C, unless other-
wise noted. For VCC = +3.0V to +3.6V, C1 = C2 = C3 = 0.1F, C4 = 1F. For VCC = +4.5V to +5.5V, C1 = 47nF, C2 = C3 = 330nF,
C4 = 1F.) (Note 2)
