The PCA9501PW,112 can support I2C bus frequencies up to 400 kHz.
Yes, the PCA9501PW,112 can be used in a multi-master I2C bus configuration, but it requires external circuitry to prevent bus contention.
To ensure reliable operation in noisy environments, use proper PCB layout techniques, add decoupling capacitors, and consider using a common-mode filter or a ferrite bead on the I2C bus lines.
The maximum cable length supported by PCA9501PW,112 depends on the specific application and the capacitance of the cable. As a general guideline, the maximum cable length is around 10 meters.
Yes, the PCA9501PW,112 can be used in a hot-swappable I2C bus configuration, but it requires proper circuit design and consideration of power sequencing to prevent bus contention and damage to the device.
