anyone know of a digital switcher that has power on/off persistence? for my project using rotary dip switches is proving too costly. i need a way to either switch 14Vdc (SPST with 6 positions). it could also just be a IC that takes one of 6 outputs high or low with the push of a button, and with each successive button push the output moves one position, etc. the catch is i need the current selection to stay persistent during power on/off cycles.
