FUNCTIONAL DESCRIPTION
Standby Function
When OE goes LOW, the oscillator stops and the output pins (OUT, OUTN) become high impedance.

Power-saving Pull-up Resistor
The OE pin pull-up resistance changes in response to the input level (HIGH or LOW). When OE is tied LOW
(standby state), the pull-up resistance becomes large, reducing the current consumed by the resistance. When
OE is open circuit, the pull-up resistance becomes small, decreasing the susceptibility to the effects of external
noise.
