#116173 - Very nice however Responding to: ???'s previous message |
It lacks the "off" function the OP secified but that is a separate input. Perhaps tri state inverters with current drive something like a 4502 or 74125 would work for him same circuit topology with the off signal driving the tri state pin. |
