NIPPON PRECISION CIRCUITS—7

FUNCTIONAL DESCRIPTION

Standby Function

The oscillator stops when INH goes LOW. When the oscillator stops, the oscillator output on Q goes high

impedance.

Power-save Pull-up Resistance

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.
