■ HANDLING DEVICES
Preventing Latch-up
Latch-up may occur in a CMOS IC if a voltage greater than VCC pin or less than VSS pin is applied to an input or
output pin or if an above-rating voltage is applied between VCC and VSS pins.
A latch-up, if it occurs, significantly increases the power supply current and may cause thermal destruction of
an element. When you use a CMOS IC, be very careful not to exceed the absolute maximum rating.
Treatment of Unused Input Pins
Do not leave an unused input pin open, since it may cause a malfunction. Handle by, for example, using a pull-
up or pull-down resistor.
About Power Supply Pins
In products with multiple VCC or VSS pins, the pins of the same potential are internally connected in the device
to avoid abnormal operations including latch-up. However, you must connect the pins to external power supply
and a ground line to lower the electro-magnetic emission level, to prevent abnormal operation of strobe signals
caused by the rise in the ground level, and to conform to the total output current rating.
Moreover, connect the current supply source with the VCC and VSS pins of this device at the low impedance.
It is also advisable to connect a ceramic bypass capacitor of approximately 0.1
F between VCC and VSS pins
near this device.
About Crystal Oscillator Circuit
Noise near the X0 and X1 pins may cause the device to malfunction. Design the printed circuit board so that X0
and X1 pins the crystal oscillator (or ceramic oscillator) , and the bypass capacitor to ground are located as
close to the device as possible.
It is strongly recommended to design the PC board artwork with the X0 and X1 pins surrounded by ground plane
because stable operation can be expected with such a layout.
Please ask the crystal maker to evaluate the oscillational characteristics of the crystal and this device.
About Mode Pins (MD0 to MD2)
These pins should be connected directly to VCC or VSS pins.
To prevent the device erroneously switching to test mode due to noise, design the printed circuit board such that
the distance between the mode pins and VCC or VSS pins is as short as possible and the connection impedance
is low.
Operation at Start-up
Be sure to execute setting initialized reset (INIT) with INIT pin immediately after start-up.
Also, in order to provide the oscillation stabilization wait time for the oscillation circuit immediately after start-up,
hold the “L” level input to the INIT pin for the required stabilization wait time (For INIT via the INIT pin, the
oscillation stabilization wait time setting is initialized to the minimum value) .
