Paralleling CMOS inverters to drive time critical signals is not a good idea because the inverters have skews between them, even if they are on the same chip (die). The skew for an improved version of the 74AC04 part (the 74LVC04) is specified as up to 1.5ns!

Modern mixers use either the same die or at last dies from the same place of the wafer to accomplish close matching. > > Cheers, > Magnus > > _______________________________________________ > time-nuts mailing list -- time-nuts@febo.com > To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts > and follow the instructions there. >

I had a TBolt die while connected to a switching supply in an environment where there were frequent power outages. The +12 VDC current drops significantly after the OCXO warms up, probably down to about 200 mA or so. Good luck. They are neat little devices.

Hi Yes, I have seen several Rb's die from what I believe were temperature related causes. Since it's an accelerated MTBF sort of thing, *proving* they were temperature related is difficult. Put another way - I believe the manufacturer's data on MTBF vs temperature is fairly accurate.
