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.
