*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.
3V operation
VDD = 2.7 to 3.6V, VSS = 0V, Ta = −40 to +85°C unless otherwise noted.
