ICS8304

Integrated Circuit Systems, Inc. ICS8304 LOW SKEW, 1-TO-4 LVCMOS / LVTTL FANOUT BUFFER FEATURES 4 LVCMOS / LVTTL outputs LVCMOS / LVTTL clock input Maximum output frequency: 200MHz Output skew: 45ps (maximum at 3.3V supply) Part-to-part skew: 500ps (maximum) Small 8 lead SOIC package saves board space 3.3V input, outputs may be either 3.3V or 2.5V supply modes Lead-Free package available 0°C to 70°C ambient operating temperature GENERAL DESCRIPTION The ICS8304 is a low skew, 1-to-4 Fanout Buffer and a member of the HiPerClockS ™ HiPerClockS™ family of High Performance Clock Solutions from ICS. The ICS8304 is characterized at full 3.3V for input VDD, and mixed 3.3V and 2.5V for output operating supply modes (VDDO). Guaranteed output and par t-to-par t skew character istics make the ICS8304 ideal for those clock distribution applications demanding well defined performance and repeatability.
