Hi all,
Possibly a simple one.. is there any way to make an inverter-based latch such as this one from RG's site power up in a known state?
I'm thinking I may be able to achieve it by holding a pin high with a cap on power-up or somethuing similar but can't get my head around it at the moment.

A few weeks ago I was looking for something similar and found this:
https://electronics.stackexchange.com/questions/186841/momentary-button-as-switch (https://electronics.stackexchange.com/questions/186841/momentary-button-as-switch)
The first answer explains how to do it. They used it for controlling a PC power supply, but the theory is the same.
In the end I used the circuit you posted as it always powered up the way I wanted. I had to play with the resistor values a bit to reduce bouncing.
Why not post the image here? =)
