16-BIT SPI GPIO EXPANDER WITH INTEGRATED LEVEL SHIFTERS

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.
