Logic 1 (60%Vs min) or no connection to pad 6 enables the oscillator output. Note: The tri-state control (enable) input pad has an internal 100k pull up resistor which allows it to be left unconnected if not used. When in tri-state mode, the output stage is disabled, but the oscillator and compensation circuit are still active (Current Consumption: 2mA typ).
