Hi,

Anyone know of a spice model for a 4069 buffer being used as an
amplifier? If there is one in pspice I can't find it.

Or come to that, info on what the params for a 4069 used as an
amplifier are.

TIA

I have a device-level model for 74HCU04, but not for 4069.

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

Hi Jim,

Thanks for the offer. I'll bear it in mind if I ever need the HC04
but for now the 4069 would suit better as the supply voltage range is
more.

Hello Malcolm,
there has been a similar question in sci.electronics.design
in November(11/18/2004). The original postings are attached.

You copy the text into notepad and then save the file with a .asc extension.
LTspice will then open it up as a schematic.

Hi Helmut,

Thanks. I'd missed that thread.
