Output duty cycle1

1. The duty cycle characteristic is checked the sample chips of each production lot.

Output disable delay time2

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.
