Figure 1. Output switching waveform
When INHN goes HIGH to LOW the Q output goes HIGH once and then becomes high impedance.
When INHN goes LOW to HIGH, the Q output goes from high impedance to normal output operation when the oscillation starts (oscillation is detected).
*) The high-impedance interval in the figure is shown as a LOW level due to the 1k
pull-down resistor connected to the Q pin (see "Measurement circuit
2" in the "Measurement Circuits" section).
