SN74LS47 BCD to 7-Segment Decoder/Driver The SN74LS47 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, high sink current outputs for driving indicators directly. Seven NAND gates and one driver are connected in pairs to make BCD data and its complement avai.
ith 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 SN74LS47 incorporates automatic leading and / or trailing-edge zero-blanking control (RBI and RBO). Lamp test (LT) may be performed at any time which the BI / RBO node is a HIGH level. This device also contains an overriding blanking input (BI) which can be used to control the lamp intensity by varying the frequency and d.
