1. Monitored in sample lots.
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.

FUNCTIONAL DESCRIPTION
Standby Function
The oscillator stops when INH goes LOW. When the oscillator stops, the oscillator output on Q goes high
impedance.
