HANDLING DEVICES
A latch-up can occur if, on this device, (a) a voltage higher than power supply voltage or a voltage lower than
GND is applied to an input or output pin or (b) a voltage higher than the rating is applied between power supply
and GND. The latch-up, if it occurs, significantly increases the power supply current and may cause thermal
destruction of an element. When you use this device, be very careful not to exceed the maximum rating.
Do not leave an unused input pin open, since it may cause a malfunction. Handle by, using a pull-up or pull-
down resistor.
Please design connecting the power supply pin of this device by as low impedance as possible from the current
supply source.
We recommend connecting electrolytic capacitor (about 10 µF) and the ceramic capacitor (about 0.01 µF) in
parallel between power supply and GND near the device, as a bypass capacitor.
Noise near the XIN pin and XOUT pin may cause the device to malfunction. Design printed circuit boards so
that electric wiring of XIN pin or XOUT pin and the resonator do not intersect other wiring.
Design the printed circuit board that surrounds the XIN pin and XOUT pin with ground.
