LM25066A: IC function check

Part Number: LM25066A

Tool/software:

Hi Team

Can you help confirm the following questions?

Due to the minimum level requirements of the circuit, our current 100khz IIC signals SCL and SDA currently have no way to meet the rise time requirement of TR<300ns in 111000000703H (LM25066APSQ/NOPB).
However, it meets the TR<1000ns requirement of the IIC specification. I would like to ask if this chip can accept the rise time TR<1000ns of SCL and SDA signals?

Thanks,

Boyan

    Hello Boyan Lu,

    Datasheet detects rise time<300nSec. With this IC can operate across all SMBus Operating Frequency (10 kHz to 100 kHz).

    I believe device can accept the TR<1000ns of SCL and SDA signals but there could be chances of data loss.

    Thanks
