What would you call this?

I am in need of a solid state relay that latches upon reception of a positive-going pulse, and holds that state until the power to it is removed. Actually something that will provide either a logic 1 or a logic 0 for another device upon reception of said pulse, and hold that state until power is removed. What would that be called, and where should I look for it? Can it build it out of OR/AND gates, like a Johnson Counter? Or can it just buy it like I can buy a CD4017? (I think that's a 0-9 counter...)Thanks for any help.Dave

Thanks for the input, and the advice RE: an SCR unlikely to hold at 200 uA. I believe I will actually have 5 mA holding current, which is a lot more than I originally thought I would have, and the SCR I am thinking of using fits that mold (the NTE5400).

'preciate it.
