This is standard and is shown in the SN datasheet:. You need to tie them to appropriate logic levels RBI should be ‘0’ if you want to display a zero. Home Questions Tags Users Unanswered.
Thank you for your interest in this question. Simply wire the respective letters a.
I’ve connected a decoder to 7-segment display as shown in figure. Spehro Pefhany k 4 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. Armandas 6, 1 decodifucador Each segment on a 7-segment display is designated a letter A-G. Like the other two most popular answers, your 7 segment display needs to be connected to the properly Outputs to Seven-segment display inputs: Then just map the pins correctly again, from datasheet:.

Would you like to answer one of these unanswered questions instead? Here is a link to a video I made on instagram of mine working using this schematic: 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.
When I connect an input, the LEDs doesn’t form numbers but decodificaador light up randomly. You can use a diode tester or a simple voltage source and a resistor to determine the pinout of your particular display.
Then just map the pins correctly again, from datasheet: The pinout is here:. The pinout is decodificqdor How to connect decoder to 7-segment display? Further, this really old chip saved a few transistors by not fully decoding inputs above 0x09, so 0x0A. 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’.
This is standard and is shown in the SN datasheet: Pin 5 should go to GND. I just want to know the right way to connect the output pins of to the pins of 7-segment display? Michael George 1, 8 34
