*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
When INHN goes LOW, the oscillator stops and the oscillator output on Q becomes high impedance.

Power-saving Pull-up Resistor
The INHN pull-up resistance changes in response to the input level (HIGH or LOW). When INHN goes LOW
(standby state), the pull-up resistance becomes large to reduce the current consumption during standby.
