Both outputs are disabled (high impedance) when pad No. 2 is taken
below 0.45＊Vcc referenced to ground (threshold). Oscillator is always
ON. Only buffer stage is disabled.
Disable current: 50 uA max. (at 0.0 V).
Disable time: 10 ns max.
At disabled mode, both outputs are enabled when pad No. 2 is taken
above 0.45＊Vcc referenced to ground (threshold).
Enable time: 10ns+one period of the output frequency max.
