Title: Seven Segment Display (with BCD Decoder)
Post by: rdbanks on June 26, 2018, 07:16:16 pm

Hi all!

Just a quick one, I'm looking for a 7 Seg Display with a decoder all built into one unit, im just wondering if anyone knows of such device, Ideally the unit will have a connector to just run the output of my device to.

I've designed it with the 74HC4511 however if anyone knows of an off the shelf unit or has any other ideas that would be great.

The unit ive designed is expansive however this part is essentially a 'shift indicator', this is a small part of the project. The display ideally needs to be a single digit, waterproof (splash proof) unit.

Thhhhaaanks!!!

How about this one of these: http://www.ti.com/lit/ds/symlink/sn74ls47.pdf (http://www.ti.com/lit/ds/symlink/sn74ls47.pdf)
Or a modern one: HEF4543B (https://assets.nexperia.com/documents/data-sheet/HEF4543B.pdf)

Edit: I think I misunderstood the question. You're looking for a 7-segment LED with build in BCD decoder? Not sure if such thing exists. Sorry.

No worries, the HEF4543B might be a good shout though!
Thanks!  ;D

The old TIL311 is a display with BCD decoder

Just built one recently: https://www.tindie.com/products/miceuz/huge-7-segment-display-module/ (https://www.tindie.com/products/miceuz/huge-7-segment-display-module/)

It's not BCD, but serial, can be daisy-chained
