BCD TO 7-SEGMENT DECODER/DRIVER The SN54 / 74LS47 are Low Power Schottky BCD to 7-Segment Decoder / Drivers consisting of NAND gates, input buffers and seven AND-OR-INVERT gates. They offer active LOW.
with a maximum reverse current of 250 µA. Indicator segments requiring up to 24 mA of current may be driven directly from the SN74LS47 high performance output transistors. Display patterns for BCD input counts above nine are unique symbols to authenticate input conditions. The SN54 / 74LS47 incorpor.
