The ICS552-03 is a low skew, single input to eight output clock buffer. Four of the outputs are exact copies of the input, while the other four are divide by 2 copies of the input. It is part of ICS' Clock BlocksTM family. See the ICS553 for a 1 to 4 low skew buffer, or the ICS552-02 for a 1 to 8 low skew buffer without divide by 2. For more than 8 outputs see the MK74CBxxx BuffaloTM series of clock drivers.
