The PCA9500BS,118 can support I2C bus frequencies up to 400 kHz.
Yes, PCA9500BS,118 can be used in a multi-master I2C bus configuration, but it requires additional 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 shielded cable to reduce electromagnetic interference (EMI).
The maximum cable length supported by PCA9500BS,118 depends on the specific application and the capacitance of the cable. As a general guideline, the maximum cable length is around 10 meters.
Yes, PCA9500BS,118 can be used in a hot-swappable I2C bus configuration, but it requires additional external circuitry to prevent bus contention and ensure reliable operation during hot-swapping.
