1. The duty cycle characteristic is checked the sample chips of each production lot.
2. Oscillator stop function is built-in. When INHN goes LOW, normal output stops. When INHN goes HIGH, normal output is not resumed until after the
oscillator start-up time has elapsed.
FUNCTIONAL DESCRIPTION
Standby Function
The oscillator stops when INHN goes LOW. When the oscillator stops, the oscillator output on Q goes high
impedance.
