LED w/ Built-in FF? Find Out Now!

[EvLer]

Does anyone know if there is such a thing?
I need a bar-graph LED with a FF built-in. The only ones I could find on digikey is a regular 10-diode LED, but I need something that would latch or hold that value until the enable changes... I could use a regular one in combination with a D-FF, but it would be nice to have something internal instead.

Thanks in advance...

I've see LEDs with built-in resistors, and LED displays with built-in latches, but not individual LEDs or bar graphs with built-in latches. I don't think there's much demand for that function.

I guess LED display with a built-in latch might work... Do you happen to know a part-number or what key-word I should search for to find it?
Thanks, berkeman

The old HP HDSP-07xx and -08xx and -09xx hex displays had a built-in decoder/driver/memory feature (another vendor makes them now). Just go to Digikey.com and do a search on HDSP-0, to get a list of the ones they carry. They're dang expensive though, so that may motivate you to brew your own with separate logic after all.
