*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 (CF5015BL×)

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