Like the other two most popular answers, your 7 segment display needs to be connected to the properly Outputs to Seven-segment display inputs: You need to tie them to appropriate logic levels RBI should be ‘0’ if you want to display a zero. I’ve connected a decoder to 7-segment display as shown in figure.

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. Home Questions Tags Users Unanswered.

When I connect an input, the LEDs doesn’t form numbers but they light up randomly. How to connect decoder to 7-segment display? Because it has attracted low-quality or decodjficador 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: By using our site, you acknowledge that you have decodifcador and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

This is standard and is shown in the SN datasheet: The pinout is here: This is standard and is shown in the SN datasheet:.

Thank you for your interest in this question. Then just map the pins correctly again, from datasheet:.

Here is a link to a video I made on instagram of mine working using this schematic: Datzsheet George 1, 8 34 Further, this really old chip saved a few transistors by not fully decoding inputs above 0x09, so 0x0A. I just want to know the right way decpdificador connect the output pins of to the pins of 7-segment display?

Note that this is an ancient display and an ancient TTL chip both are museum old and because it’s TTL open inputs will read as ‘high’.

Danny Sebahar 9. Note that this datasheet illustration is a bit messed up and the bottom segment is D not Edecodificafor next segment clockwise lower left is E.
