Low Skew, 1-TO-16 LVCMOS / LVTTL
Fanout Buffer
8343-01
DATA SHEET
General Description
The 8343-01 is a low skew, 1-to-16 LVCMOS/LVTTL Fanout Buffer.
The 8343-01 single ended clock input accepts LVCMOS or LVTTL
input levels. The ICS8343-01 operates at 3.3V, 2.5V and mixed 3.3V
input and 2.5V supply modes over the commercial temperature
range. Guaranteed output and part-to-part skew characteristics
make the 8343-01 ideal for those clock distribution applications
demanding well defined performance and repeatability.
Features
• 16 LVCMOS/LVTTL outputs
• One LVCMOS/LVTTL clock input
• CLK can accept the following input levels: LVCMOS, LVTTL
• Maximum output frequency: 200MHz
• Dual output enable inputs facilitates 1-to-16 or 1-to-8 input to
output modes
• All inputs are 5V tolerant
• Output skew: 250ps (maximum)
• Part-to-part skew: 700ps (maximum)
• Full 3.3V and 2.5V or mixed 3.3V core/2.5V operating supply
• 0°C to 70°C ambient operating temperature
• Lead-Free packaging
• Industrial temperature information available upon request
