○APPLICATION EXAMPLE
(1) Absolute maximum ratings
Absolute maximum ratings are the values which indicate the limits,
within which the given voltage range can be safely charged to the terminal.
However, it does not guarantee the circuit operation.
VCC
(2) The example of disabled circuit application
When there is a circuit not in use, it is recommended to make the
non-inverting input terminal be the potential in the common-mode
input voltage range like in Fig.1.
Circuit operation is guaranteed within “Operating Conditions”.
(3) Applied voltage to the input terminal
For normal circuit operation of comparator, please input voltage for
its input terminal within input common mode voltageVCC-1.5[V].
Then, regardless of power supply voltage,VEE+36[V] can be applied to input
terminals without deterioration or destruction of its characteristics.

(4) Operating power supply (split power supply/single power supply)
The Comparator operates if a given level of voltage is applied between VCC and
VEE. Therefore, the Comparator can be operated under single power supply or
split power supply.
(5) Power dissipation(Pd)
If the IC is used under excessive power dissipation. An increase in the chip temperature will cause
deterioration of the radical characteristics of IC.
For example, reduction of current capability. Take consideration of the effective power dissipation and thermal
design with a sufficient margin. Pd is reference to the provided power dissipation curve.
(6) Short circuits between pins and incorrect mounting
Short circuits between pins and incorrect mounting when mounting the IC on a printed circuits board,
take notice of the direction and positioning of the IC.
If IC is mounted erroneously, It may be damaged. Also, when a foreign object is inserted between
output, between output and VCC terminal or VEE terminal which causes short circuit, the IC may be damaged.
REV. A

(7) Output short circuit
If short circuit occurs between the output terminal and VCC terminal, excessive
in output current may flow and generate heat, causing destruction of the IC. Take due care.
(8) Using under strong electromagnetic field
Be careful when using the IC under strong electromagnetic field because it may malfunction.
(9) Usage of IC
When stress is applied to the IC through warp of the printed circuit board,
The characteristics may fluctuate due to the piezo effect.
Be careful of the warp of the printed circuit board.
(10) Testing IC on the set board
When testing IC on the set board, in cases where the capacitor is connected to the low impedance,
make sure to discharge per fabrication because there is a possibility that IC may be damaged by stress.
When removing IC from the set board, it is essential to cut supply voltage.
As a countermeasure against the static electricity, observe proper grounding during fabrication process
and take due care when carrying and storage it.
(11) The IC destruction caused by capacitive load
The transistors in circuits may be damaged when VCC terminal and VEE terminal is shorted with the charged
output terminal capacitor.
When IC is used as a comparator or as an application circuit, where oscillation is not activated by
an output capacitor,the output capacitor must be kept below 10[μF] in order to prevent the damage
mentioned above.
