3. Input pin noise suppression time
This IC has a built-in low-pass filter at the SK pin, the DI pin and the CS pin to suppress noise. If the supply voltage is
5.0 V, noise with a pulse width of 20 ns or less at room temperature can be suppressed by the low-pass filter.
Note that noise with a pulse width of more than 20 ns is recognized as a pulse since the noise can not be suppressed
if the voltage exceeds V_IH / V_IL.
 Precautions
• Do not operate these ICs in excess of the absolute maximum ratings. Attention should be paid to the power supply
voltage, especially. The surge voltage which exceeds the absolute maximum ratings can cause latch-up and
malfunction. Perform operations after confirming the detailed operation condition in the data sheet.
• Operations with moisture on this IC's pins may occur malfunction by short-circuit between pins. Especially, in
occasions like picking this IC up from low temperature tank during the evaluation. Be sure that not remain frost on this
IC's pin to prevent malfunction by short-circuit.
Also attention should be paid in using on environment, which is easy to dew for the same reason.
• Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in electrostatic
protection circuit.
• SII Semiconductor Corporation claims no responsibility for any and all disputes arising out of or in connection with any
infringement of the products including this IC upon patents owned by a third party.
