Usually I am easy on them. This time I need to jam it pretty good and have to drive a few CD40106 inputs below GND at 1mA-2mA. TI's data*** says 10mA is the abs max. Does anyone remember a manufacturer that might spec less than 10mA?



Which reminds me of a circuit I designed recently:

which upset some people, but I left it in because it's so cool.


I can already hear the scoffing at the design review for the circuit I am doing right now.

Did you ever use one of those blazingly fast inverters with feedback for an analog job?
