    Hi,
    I need to design a circuit or find an IC that can switch several bus lines up to 12v. They also need to go to high impedance so that they do not interfere with the other devices on the bus.
    I have used a TI device before, which works great, but only goes up to 5v max.
    Ideally, it also needs to be ESD protected.
    Anyone got any ideas?
    Much appreciated

    Can you sketch something so we know what you are talking about. Also include the names of the ICs and other devices you are connecting to your bus.

    CMOS will take you up to the 12v you need, also Maxim have a line of data switchers, depending on how you want to configure the lines?

    Look at dual peripheral drivers such as SN75450/1/2/3/4.
    or darlington arrays such as ULN2001/2/3/4.

    Well thank you all for your replies,
    The maxim switches look pretty good, plus will check out the SN75450 chips.
    Much appreciated!
