■ HANDLING DEVICES
(1) Preventing Latch-up
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 pin and GND pin. 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.
(2) Handling unused pins
Do not leave an unused input pin open, since it may cause a malfunction. Handle by, using a pull-up or pull-
down resistor.
(3) The attention when the external clock is used
Input the clock to XIN pin, and XOUT pin should be opened when you use the external clock.
Please pay attention so that an overshoot and an undershoot do not occur to an input clock of XIN pin.
(4) Power supply pins
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.
(5) Crystal oscillator circuit
Noise near the XIN and XOUT pins may cause the device to malfunction. Design printed circuit boards so
that electric wiring of XIN or XOUT pin and resonator (or ceramic oscillator) do not intersect other wiring.
Design the printed circuit board that surrounds the XIN and XOUT pins with ground.
