SM5002L series

NIPPON PRECISION CIRCUITS—6

Switching Characteristics

Current consumption and Output waveform with NPC’s standard crystal

FUNCTIONAL DESCRIPTION

Standby Function

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

impedance.

2. Oscillator stop function is built-in. When INH goes LOW, normal output stops. When INH goes HIGH, normal output is not resumed until after the

oscillator start-up time has elapsed.
