unexpected operations. Application values in these conditions should be selected carefully. If the leakage is assumed
between the VOUT terminal and the GND terminal, the pull-up resistor should be less than 1/10 of the assumed leak
resistance.
Don’t short-circuit between Output pin and VDD pin, Output pin and GND pin, or VDD pin and GND pin. When soldering the
IC on circuit board, please be unusually cautious about the orientation and the position of the IC. When the orientation is
mistaken the IC may be destroyed.
certain to use proper discharge procedure before each process of the test operation.
equipment that could sustain ESD damage, and continue observing ESD-prevention procedures in all handing, transfer
and storage operations. Before attempting to connect components to the test setup, make certain that the power supply is
OFF. Likewise, be sure the power supply is OFF before removing any component connected to the test setup.
unsettled, the couple capacitance, GND pattern of width and leading line must be considered.
Absolute Maximum Ratings are those values beyond which the life of a device may be destroyed. We cannot be defined the
failure mode, such as short mode or open mode. Therefore a physical security countermeasure, like fuse, is to be given
when a specific mode to be beyond absolute maximum ratings is considered.
Be sure to check the electrical characteristics that are one the tentative specification will be changed by temperature,
supply voltage, and external circuit.
Please put into the capacitor of 1μF or more between VDD pin and GND, and the capacitor of about 1000pF between VOUT
pin and GND, to reject noise. If extremely big capacitor is used, transient response might be late. Please confirm sufficiently
for the point.
Mal-function may happen when the device is used in the strong electromagnetic field.
The recommended parameter range for RL is 10kΩ~1MΩ. There are many factors (board layout, etc) that can affect
characteristics. Please verify and confirm using practical applications.
Connecting low-impedance capacitors to run inspections with the board may produce stress on the IC. Therefore, be
To prevent electrostatic accumulation and discharge in the assembly process, thoroughly ground yourself and any
GND terminal should be a lowest voltage potential every state.
A VDD -GND capacitor (as close connection as possible) should be used in high V
Please make sure all pins, which are over ground even if, include transient feature.
The VDD line inpedance might cause oscillation because of the detection current.
