How to design a Dual complementary CMOS switch with a Vc

Hi,

I really need help....

I'm looking an easy way to design a dual complementaty SPST switch with a single control line in order to replace an obsolete Tesas Instrument IC: TL604CP

Here is the information regardind the TL604CP:

formatting link

The TL604 is a dual complementary SPST switch with a single control input." and The TL601, TL604, TL607, and TL610 are a family of monolithic P-MOS analog switches that provide fast switching speeds with high roff/ron ratio and no offset voltage. The p-channel enhancement-type MOS switches accept analog signals up to ±10 V and are controlled by TTL-compatible logic inputs. The monolithic structure is made possible by BI-MOS technology, which combines p-channel MOS with standard bipolar transistors. "

i.e. a TTL-controlled SPDT, analog switch implemented in PMOS channel

Could it be possible to design a such switch using a CMOS CD4066 or by using a couple of fets?

Thanks a lot to helping me!

Mike

Of course you could replace this relatively undemanding integrated circuit with a discrete component design. The CD4066 is lower spec in some areas than the 604CP, so using it would depend on the exact application.

But there are loads of other analogue switches which aren't obsolete, are very inexpensive and will do the job. My first thought was the DG442DJ family - although they are quads rather than duals.

Your normal electronics components supplier will probably have suitable ones in stock for less than 1GBP.
