Jun 2004
The Enable / Disable pin has an internal pull up and if the pin is not connected the oscilaltor is enabled. Pletronics strongly recommends
connecting the Enable / Disable pin to Vcc, if the oscillator is to be enabled at all times. In the disable condition, the output becomes a
high impedance.
