HI all,
Have a small interface problem, easy cure would be to use a transistor to
switch the voltage levels though im wondering if there is a easier way (IE
less parts as im limited on space) drive voltage is 4volts, but I need to
boost that to 10V or more from a 15V supply rail..
I've been toying with a pullup and using a diode to pull the line down to
ground when the IC goes low, problem is when it goes high im forcing the 4V
line to 15volts which will probably blow the IC... can't think of any other
way apart from to use a small transistor ?
Cheers,
Chris
