The Q output becomes high impedance and the oscillator circuit stops. INHN HIGH (or open) LOW Q fO/512 High impedance Oscillator Normal operation Stopped Power-saving Pull-up Resistor The INHN pin pull-up resistance changes in response to the input level (HIGH or LOW). When INHN is tied LOW, the pull-up resistance becomes large, reducing the current consumed by the resistance. When INHN is open circuit, the pull-up resistance becomes small, decreasing the susceptibility to the effects of external noise.
