Display patterns for BCD input counts above 9 are unique symbols to authenticate input conditions. Segment identification and resultant displays are shown below. The 'LS49 circuit incorporates a direct blanking input. All of the circuits except 'LS49 have full ripple-blanking input/output controls and a lamp test input. The '48, 'LS48, and 'LS49 feature active-high outputs for driving lamp buffers or common-cathode LEDs. The '46A, '47A, and 'LS47 feature active-low outputs designed for driving, common-anode LEDs or incandescent indicators directly.
