Datasheet «SN54/74LS47»

Note that this datwsheet illustration is a bit messed up and the bottom segment is D not Eand next segment clockwise lower left is E.

Michael George 1, 8 34 You can use a diode tester or a simple voltage source and a resistor to determine the pinout of your particular display.

This is standard and is shown in the SN datasheet:. Because it has attracted low-quality or spam answers that had to be removed, posting an answer now requires 10 reputation on this site the association bonus does not count. Then just map the pins correctly again, from datasheet: Each segment on a 7-segment display is designated a letter A-G. dztasheet

Pin 5 should go to GND. Armandas 6, 1 23 I just want to know the right way to connect the output pins of to the pins of 7-segment display? When I connect an input, the LEDs doesn’t form numbers but they light up randomly. Thank you for your interest in this question. Then just map the pins correctly again, from datasheet:.

Danny Sebahar 9. Note that this is an ancient display datasheett an ancient TTL chip both are museum old and because it’s TTL open inputs will read as ‘high’. However, they don’t seem to mention that you need to have the inputs of the connected to something for it to work like you want it to.


Simply wire the respective letters a. Decodificasor the other two most popular answers, your 7 segment display needs to be connected to the properly Outputs to Seven-segment display inputs: The pinout is here:. I’ve connected a decoder to 7-segment display as shown in figure.

Home Questions Tags Users Unanswered. This is standard and is shown in the SN datasheet: The pinout is here: You need to tie them to appropriate logic levels RBI should be ‘0’ if you want to display a zero.

Spehro Pefhany k 4 Further, this really old chip saved a few transistors by not fully decoding inputs above 0x09, so 0x0A. Here is a link to a video I made on instagram of mine working using this schematic: How to connect decoder to 7-segment display?
