Lower voltage cousin of CD4007?

Hello All,

Is there a lower voltage version that is functionally similar to the
CD4007? The 74HC series doesn't seem to offer anything where FETs can be
used separately. It would be nice if there was a chip that could be used
below three volts, ideally with single cell batteries at or just below 1.5V.

There are dedicated FET arrays outside the logic world that would be
suitable but not in the price range of 20 cents.

Use an inverter as a single transister by not connecting either the
supply (nmos) or ground (pmos).

Yes, that is one method but it causes the loss of the remainder of the
chip. With the 4007, for example, that would preclude you from utilizing
the inverter on it. With single gate chips that is, of course,
different. But many of the TI versions are still not in production. At
least the web site says that they can't be ordered yet. Hopefully
they'll be ready soon.
