 Description 
 
 
  
 The XRA1200/1200P is an 8-bit GPIO expander with an I²C/-up, the XRA1200 has internal 100K ohm pull-up resistors on each I/1200P have the internal pull-up resistors enabled upon power-up in case it is necessary for the inputs to be in a known state.
 
  
 In addition, the GPIOs on the XRA1200/, the GPIOs can be outputs that are high,-state mode feature is useful for applications where the power is removed from the remote devices, but they may still be connected to the GPIO expander.
 
  
 The XRA1200 are enhanced versions of other 8-bit GPIO expanders with an I²C/1200/1200P are also pin compatible with the PCA9554A and TCA9554A.
 
  
 The XRA1200/1200P are available in 16-pin QFN and 16-pin TSSOP packages.
