3. Input pin noise elimination time
The S-93C46B/56B/66B include a built-in low-pass filter to eliminate noise at the SK, DI, and CS pins. This
means that if the supply voltage is 5.0 V (at room temperature), noise with a pulse width of 20 ns or less can be
eliminated.
Note, therefore, the noise with a pulse width of more than 20 ns will be recognized as a pulse if the voltage
exceeds V_IH/V_IL.
„ Precaution
• Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in electrostatic
protection circuit.
• SII claims no responsibility for any and all disputes arising out of or in connection with any infringement by products
including this IC of patents owned by a third party.
