DM7446A DM7447A BCD to 7- Segment Decoders/ Drivers DM7446A DM7447A BCD to 7- Segment Decoders/ Drivers General Description. Using the chip 74xx47 BCD to Seven- segment display The 74xx47 chip is used to drive 7 segment display. There will be 7 pins that you connect to the 7 pins on 7447 chip. BCD to 7- Segment Decoder/ Driver with Open- Collector Outputs General Description The DM74LS47 accepts four lines of BCDinput data / , decodes the data with seven , generates their complements internally gates having open- collector outputs to drive indicator segments directly. This datasheet has been download from:. You must use the 74xx47 with a common anode 7- segment display ( e. display you will have one pin where you apply positive voltage.
For 7447 chip you will need common anode 7 segment display. DM7447A Datasheet pdf – BCD to 7- Segment. Seven NAND gates - , its complement available to the seven decoding , one driver are connected in pairs to make BCD data - INVERT gates. Kingbright part number SA03). LE , BL, LT are all unique to the chip , used to perform various tests they are of.
Although the function is similar to a circuit made with separate components, the internal structure of the components are different in an integrated circuit. Units Description Input Output Pins Datasheet 74x100 2 dual 4- bit bistable latch 24 SN74100: 74x101 1 - ,- gated J- K negative- edge- triggered flip- flop preset. Connect / LT chip pin- 3 of 7447 to GND for Lamp Test otherwise you will see blank on hex F input. As mentioned the 7447 pulls its outputs down when segments are turned on that means that the LEDs of a 7- segment display should be connected between these , a positive voltage. This may be the 5V bar another power source at up to 15 V for the 7447. 7447 chip datasheet & application note – Datasheet Archive 7447 chip datasheet cross reference, circuit application notes in pdf format.
