Cautions 1. Do not short-circuit two or more output pins simultaneously.
2. If even one of the above parameters exceeds the absolute maximum ratings even
momentarily, the quality of the product may be degraded. The absolute maximum ratings,
therefore, specify the value exceeding which the product may be physically damaged. Use
the product well within these ratings.
The specifications and conditions shown in DC Characteristics and AC Characteristics are
the ranges for normal operation and quality assurance of the product.

Notes 1.
This is a voltage at which oscillation is always started after power application, and is applied to
oscillators of 32.768 kHz and 18.432 MHz.
2.
This is a voltage at which oscillation can be guaranteed if the voltage is lowered from the normal
operation level, and is applied to an oscillator of 32.768 kHz.
3.
This is a voltage at which oscillation can be guaranteed if the voltage is lowered from the normal
operation level, and is applied to an oscillator of 18.432 MHz.
Remark
The V

4181A has two types of power supplies. The 3.3 V power supply should be turned on at first.
Turn on/off the 2.5 V power supply depending on the status of the MPOWER pin.
