Low Skew, 1-to-2
LVCMOS / LVTTL Fanout Buffer
8302
Data Sheet
GENERAL DESCRIPTION
The 8302 is a low skew, 1-to-2 LVCMOS/LVTTL Fanout
Buffer. The 8302 hasa single ended clock input. The
single endedclock input accepts LVCMOS or LVTTL
input levels. The 8302 features a pair of LVCMOS/
LVTTL outputs. The 8302 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 part-to-part
skew characteristics make the 8302 ideal for clock distribution
applications demanding well defined performance and
repeatibility.
FEATURES
• 2 LVCMOS / LVTTL outputs
• LVCMOS / LVTTL clock input accepts LVCMOS
or LVTTL input levels
• Maximum output frequency: 200MHz
• Output skew: 25ps (typical)
• Part-to-part skew: 250ps (typical)
• Small 8 lead SOIC package saves board space
• Full 3.3V or 3.3V core, 2.5V supply modes
• 0°C to 70°C ambient operating temperature
• Lead-Free package fully RoHS compliant
