Hi all,
I have been looking for days not so eventaully have given up and came here for advice.
I have a power line (3.3v 3ma max) that I want to turn off/on but I also need it to be latching so, my MCU toggles it and it turn on then toggles it and it turn off. I have looked at the logic familes but get a little confused trying to remember what a MUX vs SPST vs Analog switch vs J-K Flip flop can do and which is best so I thought I'd ask here.
The MCU wil be in low power in between events and so does not want to be driving a load / pin, also the solutions must be very LOW power ideally <1ua
Basically I'm looking for a very low power, MCU controllable latching SPST switch.
Thx
Steve
