GLITCH-FREE CLOCK MULITPLEXER
Description
The ICS580-01 is a clock multiplexer (mux) designed to
switch between two clock sources with no glitches or short
pulses. The operation of the mux is controlled by an input
pin but the part can also be configured to switch
automatically if one of the input clocks stops. The part also
provides clock detection by reporting when an input clock
has stopped.
For a clock mux with zero delay and smooth switching, see
either the ICS581-01 or the ICS581-02.
