Hallo Nick, > I was thinking to simply use a DIODE and have the device > drive the line high when not needed. That's OK. This is the same way the XE1541-interface works. > I can never remember which way to face the DIODE |\ | | \ | device ----+ >+---- CNT1 / SP1 | / | |/ | The cathode (the black line at the top of the triangle) is marked as a black band around the diode (silver when diode is black itself). For speed reasons you better can use so-called Scottky-diodes (spelling ??). > but do you think that this will be enough to avoid > pulling on CNT1 and SP1?
