The PCA9501D,118 can support I2C bus frequencies up to 400 kHz.
The PCA9501D,118 can support up to 112 devices on the I2C bus, assuming a 7-bit address space.
The maximum cable length for the PCA9501D,118 I2C bus depends on the capacitance of the bus and the frequency of operation. As a general guideline, the maximum cable length is around 10 meters at 100 kHz and 1 meter at 400 kHz.
Yes, the PCA9501D,118 supports hot-swapping of devices on the I2C bus, but it requires proper circuit design and device implementation to ensure reliable operation.
The power consumption of the PCA9501D,118 depends on the operating frequency and the load on the I2C bus. Typically, the power consumption is around 1.5 mA at 100 kHz and 3.5 mA at 400 kHz.
