Armandas 6, 1 23 This is standard and is shown in the SN datasheet: When I connect an input, the LEDs doesn’t form numbers but they 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:. How to connect decoder to 7-segment display?

Home Questions Tags Users Unanswered. Would you like to answer one of these unanswered questions instead? This is standard and is shown in the SN datasheet:.
Like the other two most popular answers, your 7 segment display needs to be connected to the properly Outputs to Seven-segment display inputs: Further, this really old chip saved a few transistors by not fully decoding inputs above 0x09, so 0x0A.
Pin 5 should go to GND. 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. The pinout is here: 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. The pinout is here:.

Simply wire the respective letters a. Here is a link to a video I made on instagram of mine working using this schematic: Then just map the pins correctly again, from datasheet: Danny Sebahar 9.
Decoxificador connected a decoder to 7-segment display as shown in figure. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.
You need to tie them to appropriate logic levels RBI should be ‘0’ if you want to display a zero.
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’. I just want to know the right way to connect the output pins of to the pins of 7-segment display?
Thank you for your interest in this question. Each segment on a 7-segment display is designated a letter A-G. Michael George 1, 8 34
