Re: HCT4051 leakage



Hello John,

Indications are that everybody's 0.1 uA max spec is wildly
pessimistic, but I was wondering if anybody knows more, before I have
to drag my *** into the lab and make actual measurements. It's a lot
easier to sit here and type and eat bon-bons.


Actually channel-to-channel it's 0.4uA for the '51, less for the '52 and '53. Sez TI.


However, the difference in RDSon from channel to channel can be up to 10ohms or so. I have never seen that much in practice but if this matters can't you sink in a reference current instead of a voltage?

And watch our for fingerprints, flux and bon-bon residue ;-)

Regards, Joerg
