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