SN74LS47N Description
The SN74LS47N is a Low Power Schottky BCD to 7-Segment Decoder/Driver with active-low outputs that can be used to drive common-anode LEDs or incandescent indicators directly. This IC drives lamp buffers or common-cathode LEDs. With the exception of the LS49, all of the circuits offer full ripple-blanking input/output controls and a lamp test input. For BCD input counts of more than 9, display patterns are unique symbols that authenticate input conditions. Automatic leading and/or trailing-edge zero-blanking control is included in its circuitry (RBI\ and RBO\). When the BI/RBO node is at a high level, these types of lamp tests (LT/) can be done at any time.
