As far as the case type is concerned, the cut smart buffer is available in 20-TSSOP (0.173, 4.40mm Width). It is available in the case Tape & Reel (TR). For normal operation, 350MHz is the maximum value. As far as I can tell, it is mounted by Surface Mount. A classification of Fanout Buffer (Distribution), Multiplexer is assigned to this electronic part. Temperature -40°C~85°C is recommended for reliable performance. The clock switch should be able to be powered by a 3.135V~3.465V V source. The output of it is LVDS. The ICS8545-02 family contains it.
