I am looking for gate switch, either single pole or double pole, capable of independently switching at a frequency up to 1kHz?
I have 3.3 volts dc supply with which to drive the switch but need it to be capable of the isolated switching of 15 volts dc.
Thak you so much.

You will find that TI's analog switches are typically capable of switching a 1 kHz signal.
Though TI offers switches that support input voltage beyond supply, such as TMUX1574, the maximum I/O voltage TMUX1574 can support is VDD x 2. The maximum VDD TMUX1574 can support is 5.5V.
Most of TI's analog switches support a maximum I/O voltage up to the switch's supply voltage. In order to switch a signal of 15V, you will need to choose a switch that supports higher VDD and I/O voltage, such as a switch in the TMUX61xx family (depending on the configuration and channels needed).
What is your application and end equipment where you need to switch an I/O voltage much larger than your supply?
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

Thank you once again.
