HANDLING DEVICES
1.
Preventing latch-up
CMOS IC chips may suffer latch
-
up under the following conditions:
A voltage higher than V
CC
or lower than V
SS
is applied to an input or output pin.
A voltage higher than the rated voltage is applied between V
CC
and V
SS
pins.
The AV
CC
power supply is applied before the V
CC
voltage.
Latch-up may increase the power supply current drastically, causing thermal damage to the device.
For the same reason, also be careful not to let the analog power-supply voltage (AV
CC
, AVRH) exceed the digital
power-supply voltage.
Handling unused pins
2.
Leaving unused input pins open may result in misbehavior or latch-up and possible permanent damage to the
device. Therefore they must be pulled up or pulled down through resistors. In this case those resistors should
be more than 2 k
.
Unused bidirectional pins should be set to the output state and can be left open, or the input state with the above
described connection.
Power supply pins (V
CC
/V
SS
)
If there are multiple V
CC
and V
SS
pins, that are designed to be set to the same potential are connected the
inside of the device to prevent malfunctions such as latch-up.
To reduce unnecessary radiation, prevent malfunctioning of the strobe signal due to the rise of ground level,
and observe the standard for total output current, be sure to connect the V
CC
and V
SS
pins to the power supply
and ground externally. Connect V
CC
and V
SS
pins to the device from the current supply source at a low imped-
ance.
As a measure against power supply noise, connect a capacitor of about 0.1
μ
F as a bypass capacitor between
V
CC
and V
SS
pins in the vicinity of V
CC
and V
SS
pins of the device
3.
4.
Mode Pins (MD0 to MD2)
Connect the mode pins directly to V
CC
or V
SS
pins. To prevent the device unintentionally entering test mode due
to noise, lay out the printed circuit board so as to minimize the distance from the mode pins to V
CC
or V
SS
pins
and to provide a low-impedance connection.
