LTC6991H

TimerBlox: Resettable, Low Frequency Oscillator

Linear Technology 

LTC6991

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.
