Relays constantly on using a multiplexer.

hi

i working on project consisting of 8 relays.

is possible use multiplexer control relays

by cycling thru channels , providing power
needed relay thru multiplexer's common.

as far know wouldnt problem turn
only 1 relay on, if use multiplexer

only 1 channel can output voltage @ time.

i pretty sure relays respond slower than
the arduino's clock.

so wonder if looping thru 8 channels fast
could keep relays on constantly?

if would, should damage relays?

is there better yet simple way this?

thanks.

the simple way serial-in/parallel-out shift register.  gives 8 separate outputs can individually controlled.
