PIN FUNCTIONS (DCB/S6)
GND (Pin 5/Pin 2): Ground. Tie to a low inductance ground
plane for best performance.
OUT (Pin 6/Pin 6): Oscillator Output. The OUT pin swings
from GND to V+ with an output resistance of approximately
30Ω. When driving an LED or other low impedance load
a series output resistor should be used to limit source/
sink current to 20mA.
