OK, so the reason for keeping the pulse short is battery conservation, not some precise time requirement. That makes the solution simpler and much less critical.THanks for the reply, I'll be reading it with an IR receiver so not worried about seeing it, just about saving power by keeping the pulse short.
In which case, you need Danko’s circuit. You will be surprised how much current HC14s use!OK, so the reason for keeping the pulse short is battery conservation, not some precise time requirement. That makes the solution simpler and much less critical.
That is why I suggested the CD4049 circuit. The current is what the load draws.In which case, you need Danko’s circuit. You will be surprised how much current HC14s use!
