TIL311

[sonnytiger]

I did a little video on this guy because I always thought it was pretty cool. If you have never heard of it, it's a single digit hex display with built in logic to drive the leds, all you have to do is interface with four data pins and a latch.

These little displays is really cool, and they is very useful for circuits without a mcu.

Also, there is the TIL306 with a decade counter and BCD output. Very useful.

[sonnytiger]

That one is cool, seems rather similar to the 311, though the package seems really long compared to the digit size haha.

[Thor-Arne]

Yes, packages is rather large.
But compared with using separate counters/latches/drivers a lot of board space is saved.

These displays used to be high end and very expensive. They are not 7 segment, they do round corners and look much better.

The problem with these ancient parts is power consumption. 5v only and typically 105mA to while displaying a zero, max to display a zero is 180mA.

The power for a TIL311 two digit display could run a 5" LCD with backlight.

[sonnytiger]

Sure they draw a lot of power, but, they just look so... awesome!

They are still very expensive! 0_o
