Analog Switch Subcircuit

I posted this to the LTspice group, but thought it might be of interest here... a 4016 switch...

(Caution the MOS devices are single line, so fix it up if your copy wraps.)

I love to cook with wine.     Sometimes I even put it in the food.

I ocassionally used the improved CD4066 and 74HC4066 in the past. Any chance of adapting your model to these devices?

Even though Motorola no longer exists (at least that division) I'll have to check the dates and see when the NDA's run out :-)

However, as you may remember from my 74HC4051,2,3 schematic posting, these are quite hairy models at the device level.

I'll ponder doing these as behavioral models... easier convergence and faster simulations... that's why LTspice is so "fast"... mostly behavioral rendering of parts. ...Jim Thompson

I found the following which looks like I re-did it to modern 4066 specifications....
