SM5009 series
FUNCTIONAL DESCRIPTION
Standby Function
5009 AL× series
When INH goes LOW, the oscillator stops and the oscillator output on Q becomes high impedance.
5009AH×, AK×, AN×, CN× series
When INH goes LOW, the output on Q becomes high impedance, but internally the oscillator does not stop.

Power-save Pull-up Resistance (AL× series only)
The INH pull-up resistance changes in response to the input level (HIGH or LOW). When INH goes LOW
(standby state), the pull-up resistance becomes large to reduce the current consumption during standby.
