... Although pin-to-pin and I compatible with the PCF8575, software changes are required due to the enhancements and are discussed in Application Note AN469. The PCA9535 is identical to the PCA9555 except for the removal of the internal I/O pull-up resistor which greatly reduces power consumption when the I/Os are held LOW. ...
