15 / 18 page ![]() SM5009 series NIPPON PRECISION CIRCUITS—15 5 V operation: VDD = 4.5 to 5.5 V, VSS = 0 V, Ta = −40 to 85 °C unless otherwise noted. Current consumption and Output waveform with NPC’s standard crystal FUNCTIONAL DESCRIPTION Standby Function AH, AK, AN, CN series When INH goes LOW, the output on Q becomes high impedance, but internally the oscillator does not stop. AL series When INH goes LOW, the oscillator stops and the oscillator output on Q becomes high impedance. 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.
