SM5010 series
FUNCTIONAL DESCRIPTION
Standby Function
5010AH×, AK×, AN×, BH×, BK×, BN×, DN×, FN×, FH×, HN×, HK× series
When INHN goes LOW, the output on Q becomes high impedance, but internally the oscillator does not stop.
5010CL× series
When INHN goes LOW, the oscillator stops and the oscillator output on Q becomes high impedance.
5010EA× series
When INHN goes LOW, the oscillator stops and the oscillator output on Q becomes LOW.

Power-saving Pull-up Resistor (CL series only)
The INHN pull-up resistance changes in response to the input level (HIGH or LOW). When INHN goes LOW
(standby state), the pull-up resistance becomes large to reduce the current consumption during standby.
