Glitch-Free Clock Mulitplexer

The 580-01 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 581-01 or the 581-02.


  • 16-pin SOIC and 16-pin TSSOP packages available
  • Pb (lead) free package
  • No short pulses or glitches on output
  • Operates from 2 to 220 MHz
  • Low skew outputs
  • Clock detect feature
  • Ideal for systems with back-up or redundant clocks
  • Selectable timeouts for clock detection
  • Separate supply voltages allow power supply voltage translation
  • Operates from 2.5 V to 5 V
