Composition of all other characters, including display patterns for BCD inputs above nine, is identical. The HD74LS247 features active-low outputs designed for driving indicators directly. All of the circuits have full rippleblanking input / output controls and a lamp test input.
Segment identification and resultant displays are shown below. Display patterns for BCD input conditions.
