16-BIT SPI GPIO EXPANDER WITH INTEGRATED LEVEL SHIFTERS
NOTE: The Vcc comes from VCCP pin for the GPIOs and the VCC pin for the other signals;
NOTES:
1. For SPI input signals (SI, SCL) & GPIOs, A0, A1 and A2 signals;
2. For SPI output signal SO;
3. For GPIOs;
4. For IRQ# signal;
Test 1: SCL frequency is 10 MHz with internal pull-ups disabled. All GPIOs are configured as inputs. All inputs are steady at
VCC or GND. Outputs are floating or in the tri-state mode.
Test 2: SCL frequency is 10 MHz with internal pull-ups enabled. All GPIOs are configured as inputs. All inputs are steady at
VCC or GND. Outputs are floating or in the tri-state mode.
