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