NB3N551
3.3 V / 5.0 V Ultra-Low Skew 1:4 Clock Fanout Buffer
Description The NB3N551 is a low skew 1−to 4 clock fanout buffer, designed
for clock distribution in mind. The NB3N551 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 three−states the outputs when low.
Features
