The 7447 feature active-LOW outputs
designed for driving common-anode LEDs or incandescent
indicators directly. All of the circuits have full ripple-blanking
input/output controls and a lamp test input. Segment
identification and resultant displays are shown on a following
page. Display patterns for BCD input counts above nine
are unique symbols to authenticate input conditions.
