Hello, I am using TCA9539-Q1 (IO Expander). I am attaching my schematic. I want to use IO expander as OUTPUT so I have configured both port as output. I need the output to be low at power up so I write "0x00" to both output port (as datasheet says output is by default high). On writing the output port as "0x00" ; All pins becomes high for ~89us ; because of this my load becomes high for some time which is undesired behavior.
