Description
PI6C18551 is a low skew, low noise and high-speed clock buffer
for computing, networking and communication applications. It is
a non-inverting buffer with four outputs from a single input. The
outputs are controlled by output enable pin (OE), outputs are tri-states
when OE is LOW, and outputs are enabled when OE is HIGH.
