PCA9548A: Fast Mode I2C Fall Time Consult

Part Number: PCA9548A


Hi Team,

Customer uses our PCA9548 in I2C Fast Mode(400kHz), and finds out the I2C fall time is around 6ns. However our D/S requires the min fall time should beyond 20+0.1Cb ns, they want to know any potential risks they may encounter when this spec is not satisfied? Is that okay to do that? Thanks.

Best,

Stanley
