AC CHARACTERISTICS
V_CC = 4.75 to 5.25 V; V_STB = V_CC; V_BAT = 6 V to 27 V; T_amb = −40 to +125 °C; unless otherwise specified. All voltages
are defined with respect to ground. Positive currents flow into the IC. All parameters are guaranteed over the
temperature range by design, but only 100% tested at 25 °C.
