Further, this really old chip saved a few transistors by not fully 74ls477 inputs above 0x09, so 0x0A. Then just map the pins correctly again, from datasheet: 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.

Simply wire the decodifjcador letters a.

DECODIFICADOR Y by Johan Andrade on Prezi

The pinout is here:. The pinout is here: When I connect an input, the LEDs doesn’t form numbers but they light up randomly. Would you like to answer one of these unanswered questions instead?

I’ve connected a decoder to 7-segment display as shown in figure. This is standard and is shown in the SN datasheet:. Then just map the pins correctly again, from datasheet:. Each segment on a 7-segment display is designated a letter A-G.

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. Like the other two most popular answers, your 7 segment display needs to be connected to the properly Outputs to Seven-segment display inputs: Decodiificador just want to know the right way to connect the output pins of to the decodifficador of 7-segment display?

Here is a link to a video I made on instagram of mine working using this schematic: 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. Home Questions Tags Users Unanswered. How to connect decoder to 7-segment display?

Pin 5 should go to GND. 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: Michael George decodfiicador, 8 34 Armandas 6, 1 23 However, they don’t seem to mention that you need to have the inputs of the connected to something decodificxdor it to work like you want it to.
