Further, this really old chip saved a few transistors by not fully decoding inputs above 0x09, so 0x0A. By using our site, you acknowledge that you have read decodififador understand our Cookie PolicyPrivacy Policyand our Terms of Service.

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:. Then just map the pins correctly again, from datasheet: However, they don’t seem to mention that you need to have the inputs of the connected to decodifocador for it to work like you want it to.


Each segment on a 7-segment display is designated a letter A-G.

The pinout is here: Like the other two most popular answers, your 7 segment display needs to be connected to the properly Outputs to Seven-segment display inputs: Thank you for your interest in this question. How to connect decoder to 7-segment display?

ON Semiconductor – datasheet pdf

I’ve decodificadod a decoder to 7-segment display as shown in figure. Home Questions Tags Users Unanswered. I just want to know the right way to connect the output pins of to the pins of 7-segment display? The pinout is here:.

Would you like to answer one of these unanswered questions instead? When I connect an input, the LEDs doesn’t form numbers but they light up randomly. Danny Sebahar 9.

Here is a link to a video I made on instagram of mine working using this schematic: You need to tie them to appropriate logic levels RBI should be ‘0’ if you want to display a zero. Simply wire the respective letters a. Note that this datasheet illustration is a bit decocificador up and the bottom segment is D not Eand next segment clockwise lower left is E.

Spehro Pefhany k 4 Pin 5 should go to GND. Armandas 6, 1 23 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:.
