The 556-04 is a low-skew, crystal input compatible clock buffer with oscillator. This device offers the lowest skew. See the 552-02 for a 1-to-8 low skew buffer. For more than eight outputs see the MK74CBxxx BuffaloTM series of clock drivers. IDT makes many non-PLL and PLL-based low-skew output devices. Contact IDT for all of your clocking needs.


  • Extremely low-skew outputs (50 ps maximum)
  • Packaged in 8-pin SOIC
  • Operating voltages of 2.5 to 5.0 V
  • Low-power CMOS technology
  • Industrial temperature range
  • Pb (lead) free package
