NB3L553 Datasheet, PDF (1/6 Pages) ON Semiconductor – 2.5 V / 3.3 V / 5.0 V 1:4 Clock Fanout Buffer

NB3L553
2.5 V / 3.3 V / 5.0 V
1:4 Clock Fanout Buffer
Description
The NB3L553 is a low skew 1−to 4 clock fanout buffer, designed for
clock distribution in mind. The NB3L553 specifically guarantees low
output−to−output skew. Optimal design, layout and processing
minimize skew within a device and from device to device.
The output enable (OE) pin tri−states the outputs when low.
Features
• Input/Output Clock Frequency up to 200 MHz
• Low Skew Outputs (35 ps)
• Output Enable Mode Three−States Outputs
• Operating Range: V_DD = 2.375 V to 5.25 V
• Ideal for Networking Clocks
• Packaged in 8−pin SOIC
• Industrial Temperature Range
• These are Pb−Free Devices
