Clock Output 4
Negative supply voltage; Connect to ground, 0 V
Positive supply voltage (3.0 V to 5.5 V)
Output Enable for the clock outputs. Outputs are enabled when HIGH or when left
open; OE pin has internal pull−up resistor. Three−states outputs when LOW.
(DFN8 only) Thermal exposed pad must be connected to a sufficient thermal
conduit. Electrically connect to the most negative supply (GND) or leave uncon-
nected, floating open.
