    Hi ,

    i want a relay driver with more input channels. As of now used ULN28003 for driving 8 relays, now i want drive more than 8 relays,

    is there any Relay driver IC which drives more relays other than 8...??

    hi ,
    If you go with 2xULN2803 cost will be more

    I want to drive 9 relays right now and much more like 14 relays in future so keeping these two i want single relay driver IC with more than 8 channels.

    So using 2 octal relay driver would cost to my design.

    so i am looking for ic with more than 8 channels.

    i tried to checked on alldatasheet.net regarding ics of more than 8 inputs and output driver to relays
    but no data appear. i think the last resort is by using 2 ics if you need more than 8.
