16-BIT SPI GPIO EXPANDER WITH INTEGRATED LEVEL SHIFTERS
REV. 1.0.0
Test 3: All inputs are steady at VCC or GND to minimize standby current. If internal pull-up is enabled, input voltage level
should be the same as VCC. SCL and SI are at GND. CS# is at VCC. All GPIOs are configured as inputs. Outputs are left
floating or in tri-state mode.
