This is standard and is shown in the SN datasheet: When I connect an input, the LEDs doesn’t form numbers but they decodkficador up randomly. Further, this really old chip saved a few transistors by not fully decoding inputs above 0x09, so 0x0A.
Then just map the pins correctly again, from datasheet:. Armandas 6, 1 23 Simply wire the respective letters a. 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.

The pinout is here: However, decodiicador 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.
Pin 5 should go to GND. Note that this datasheet illustration is a bit messed up and the bottom segment is D not Eand next segment clockwise lower left is E. This is standard and is shown in the SN datasheet:.

Would you like to answer one of these unanswered questions instead? I’ve connected a decoder to 7-segment display as shown in figure.
Danny Sebahar 9. Thank you for your interest in this question. Here is a link to a video I made on instagram of mine working using this schematic: 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’.
The pinout is here:. I just want to know the right way to connect the output pins of to the pins decoeificador 7-segment display?
Spehro Pefhany k 4 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 can use a diode tester or a simple voltage source and a resistor to determine the pinout of your particular display.

You need to tie them to appropriate logic levels RBI should be ‘0’ if you want to display a zero.
