[Handling
Precautions]
1.
Design
precautions
1)
Never
exceed
the
absolute
maximum
ratings,
even
for
a
very
short
time.
2)
Take
precautions
against
the
influence
of
heat
in
the
environment,
and
keep
the
temperature
around
the
LSI
as
cool
as
possible.
3)
Please
note
that
ignoring
the
following
may
result
in
latching
up
and
may
cause
overheating
and
smoke.
-
Do
not
apply
a
voltage
greater
than
the
specified
voltages
for
the
Vdd5
terminal
to
the
input/output
terminals
and
do
not
pull
them
below
GND.
-
Please
consider
the
voltage
drop
timing
when
turning
the
power
ON/OFF.
Consider
power
voltage
drop
timing
when
turning
ON/OFF
the
power.
-
Make
sure
you
consider
the
input
timing
when
power
is
applied.
-
Be
careful
not
to
introduce
external
noise
into
the
LSI.
-
Hold
the
unused
input
terminals
to
+5
V
or
GND
level.
-
Do
not
short-circuit
the
outputs.
-
Protect
the
LSI
from
inductive
pulses
caused
by
electrical
sources
that
generate
large
voltage
surges,
and
take
appropriate
precautions
against
static
electricity.
4)
Provide
external
circuit
protection
components
so
that
overvoltages
caused
by
noise,
voltage
surges,
or
static
electricity
are
not
fed
to
the
LSI.
5)
Turn
the
Vdd5
(+5V)
and
Vdd3
(+3.3V)
supply
ON/OFF
at
the
same
time,
or
as
nearly
the
same
time
as
possible.
Turning
the
power
on
to
either
voltage
supply
may
cause
a
"break-through
current"
to
flow.
Continued
application
of
a
"break-through
current"
may
generate
heat
and
shorten
the
life
of
the
LSIs.
2.
Precautions
for
transporting
and
storing
LSIs
1)
Always
handle
LSIs
carefully
and
keep
them
in
their
packages.
Throwing
or
dropping
LSIs
may
damage
them.
2)
Do
not
store
LSIs
in
a
location
exposed
to
water
droplets
or
direct
sunlight.
3)
Do
not
store
the
LSI
in
a
location
where
corrosive
gases
are
present,
or
in
excessively
dusty
environments.
4)
Store
the
LSIs
in
an
anti-static
storage
container,
and
make
sure
that
no
physical
load
is
placed
on
the
LSIs.
3.
Precautions
for
installation
1)
In
order
to
prevent
damage
caused
by
static
electricity,
pay
attention
to
the
following.
-
Make
sure
to
ground
all
equipment,
tools,
and
jigs
that
are
present
at
the
work
site.
-
Ground
the
work
desk
surface
using
a
conductive
mat
or
similar
apparatus
(with
an
appropriate
resistance
factor).
However,
do
not
allow
work
on
a
metal
surface,
which
can
cause
a
rapid
change
in
the
electrical
charge
on
the
LSI
(if
the
charged
LSI
touches
the
surface
directly)
due
to
extremely
low
resistance.
-
When
picking
up
an
LSI
using
a
vacuum
device,
provide
anti-static
protection
using
a
conductive
rubber
pick
up
tip.
Anything
which
contacts
the
leads
should
have
as
high
a
resistance
as
possible.
-
When
using
a
pincer
that
may
make
contact
with
the
LSI
terminals,
use
an
anti-static
model.
Do
not
use
a
pincer,
if
possible.
-
Store
unused
LSIs
in
a
PC
board
storage
box
that
is
protected
against
static
electricity,
and
make
sure
there
is
adequate
clearance
between
the
LSIs.
Never
directly
stack
them
on
each
other,
as
it
may
cause
friction
that
can
develop
an
electrical
charge.
2)
Operators
must
wear
wrist
straps
which
are
grounded
through
approximately
1M-ohm
of
resistance.
3)
Use
low
voltage
soldering
devices
and
make
sure
the
tips
are
grounded.
4)
Do
not
store
or
use
LSIs,
or
a
container
filled
with
LSIs,
near
high-voltage
electrical
fields,
such
those
produced
by
a
CRT.
5)
To
preheat
LSIs
for
soldering,
we
recommend
keeping
them
at
a
high
temperature
in
a
completely
dry
environment,
i.e.
125
o
C
for
24
hours.
The
LSI
must
not
be
exposed
to
heat
more
than
2
times.
