DRV8871: The maximum rise time and fall time of IN1/2(logic input)

Part Number: DRV8871

Hello,

Regarding to IN1/2(logic input) on DRV8871, my customer is asking a question.

(Question)

･How is rise time and fall time in IN1/2?

I am understanding that generally, the maximum rise time and fall time of CMOS logic(Vcc5V) are approximately 20ns/V.

Is it same as above value?

They use very slow rise time and fall time(20us~) signal as IN1/2 and they are facing the anomalous oscillation on this device output.

Regards,
