When division by zero is attempted, an overflow condition will result, and error symbol
"E" and a zero are displayed.
When the integer part of result exceeds 10 digits, the display will show 10 most significant
digits of result divided by 10+10 and "E".
When the integer part of result exceeds 19 digits, display will show a zero and "E".
When the integer part of result in memory register exceeds 10 digits at memory
calculation, display will show a zero and "E", and previous data will be kept in memory
resister.
When an overflow occurs on the way of add-on/discount calculation, display will show a
zero and "E".
When square root of any negative number is attempted, "E" and square root of absolute
value are displayed.
In overflow condition, any operation or numeral entry will be inhibited.
Clearing Overflow Condition
The resulting overflow condition can be cleared by depressing ON/C/CE .
At memory overflow condition, depression of ME after ON/C/CE will recall the previous
memory data.
At the condition of exceeding capacity overflow occurred in chain calculation, depression
of ON/C/CE will reset the error symbol "E", and you can continue the calculation using
the displayed data.

Keys for Calculator
(1) Data Keys
The data keys consist of numeral keyslil , throughEI and a decimal point key|:| .
The first of a sequence of data keys will clear the contents of display register before being
entered. The decimal point key will be accepted the first time it is depressed during
calculations.
(2) Arithmetic Operation Keys
The arithmetic operation keys include the plus I, minus E ' multiply I, divide El '
equalEI, percent. ' square root ' memory add ' memory subtract El, sign
change -, data shift-.
Depression of this key conditions the calculator for addition of display register to
upper register.
If the calculator was previously conditioned for add, subtract, multiply or device,
those operation would be performed with the resultant intermediate sum,
difference, product or quotient displayed and previous modes and reset, and
calculator stores add command.
In the successive depressions of this key, the first will perform the previously
enabled mode and more than twice depressions will be ignored.
IC-l Depression of this key performs the same function as the. key with the exception
that calculator stores subtract mode.
Depression of this key conditions the calculator for multiplication of upper register
and display register.
If the calculator was previously conditioned for add, subtract multiply or divide,
those operation would be performed with the resultant intermediate sum,
difference, product or quotient displayed.

exception that the calculator result or displayed number is subtracted from the
memory register.
El Depression of this key following numeral entry will perform the previously
enabled mode.
If no number has been entered, the displayed number will be used to perform
the previously enabled mode. If no mode are enabled, this key will be ignored. If
multiplication or division are enabled, constant mode operations are performed
by termination a sequence of operations with the El key, entering a new
number and depressing the IE key.
Any key sequence terminated with, E-l key will not require the use of
ON/C/CE key before a new operation sequence can be initiated.
% If the calculator was previously conditioned for addition, or subtraction or
multiplication or divination, calculations would be performed as follows.
a+b- a+a-b/100
a-blE a-a.b/100
a x b a.b/100
a .= b 100 a/b
If no mode are enabled, this key will be ignored. If multiplication or division are
enabled, constant mode operations are performed by terminating a sequence of
operation with the .key, entering new number and depressing the. key.
Depression of this key will perform the previously enabled mode and add the
result to memory register and leave the result in the display register.
If no modes are enabled, the displayed number is added to memory register by
this key.
Any key sequence terminated with- will not require the use of the
key before a new operation sequence can be initiated.

c) PURCHASER shall return these packing materials to VENDOR on VENDOR's demand.
9. Storage criteria
Solid state chips, unlike packaged devices, are non-hermetic devices normally fragile and small in
physical size, and therefore, require special handling considerations as follows :
Chips must be stored under proper conditions to insure that they are not subjected to a
moist and/or contaminated atmosphere that alter their electrical, physical, or mechanical
characteristics.
After the shipping container is opened, the chips must be stored under the following
conditions :
A. Storage temperature, 40°C max.
B. Relative humidity, 50% max.
C. Clean, dust-free environment.
The user must exercise proper care when handling chips or wafers to prevent even the
slightest physical damage to the chip.
During mounting and lead bounding of chips the user must use proper assembly techniques
to obtain proper electrical, thermal, and mechanical performance.
After the chip has been mounted and bounded, any necessary procedure must be followed
by the user to insure that these non-hermetic chips are not subjected to moist or
contaminated atmosphere which might cause the development of electrical conductive paths
across the relatively small insulating surfaces.
In addition, proper consideration must be given to the protection of these devices from
other harmful environments which could conceivably adversely affect their proper
performance.

10.Hand|ing criteria
The user should find the following suggested precautions helpful in handling chips.
In any event, because of the extremely small size and fragile nature of chips, care should be taken
in handling these devices.
Grounding
a) Bonders, pellet pickup tools, table tops, trim and form tools, sealing equipment, and
other equipment used in chip handling should be properly grounded.
b) Operator should be properly grounded.
In-process handling
a) Assemblies or subassemblies of chips should be transported and stored in conductive
carriers.
b) All external leads of the assemblies or subassemblies should be shorted together.
VISUAL INSPECTION CRITERIA
1. Visual inspection magnification shall be 40 x in principle.
2. Defects defined :
Thickness
See the technical data sheet.
Chip and crack
A die shall be rejected if :
a) Any crack of chip extends greater than 35pm in length into the inside of the scribble
line. (see Fig.1)
