______________________________________________________________Pin Description
____________________________Typical Operating Characteristics (continued)
(All curves generated using the inverter circuit shown in the
Typical Operating Circuits with LV = GND and TA = +25°C, unless other-
wise noted. Test results also valid for doubler mode with LV = OUT and TA = +25°C. All capacitor values used are those recom-
mended in Table 3, unless otherwise noted. The output resistance curves represent the resistance of the device itself, which is RO in
the equation for ROUT shown in the Capacitor Selection section.)
