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 input counts above 9 are unique symbols to authenticate input conditions.
The '46A, '47A, '48, 'LS47, and 'LS48 circuits incorporate Automatic leading and/or trail 83e ing-edge zero-blanking control (RBI and RBO). Lamp test (LT) of these types may be performed at any time when the BI/RBO node is at a high level. All types (including the '49 and 'LS49) contain an overriding blanking input (BI), which CAN be used to control the lamp intensity by pulsing or to inhibit the outputs. Inputs and outputs are entirely compatible for use with TTL Logic outputs.
The SN54246/SN74246 and '247 and the SN54LS247 SN74LS247 and 'LS248 compose the and the with tails and were designed to offer the designer a choice between two indicator fonts.
