It provides a simple solution when additional I/Os are needed while keeping interconnections to a minimum, for example, in battery-powered mobile applications for interfacing to sensors, push buttons, keypad, etc. It can operate from 1.65V to 4V on the GPIO -port side and 1.65V to 3.6V on the SDA/SCL side. This allows the PI4IOE5V6408 to interface with next generation microprocessors and microcontrollers on the SDA/SCL side, where supply levels are dropping down to conserve power. The bidirectional voltage -level translation in the PI4IOE5V6408 is provided through VDD(I2C_bus). VDD(I2C_bus) should be connected to the VDD of the external SCL/SDA lines. The voltage level on the GPIO -port of the PI4IOE5V6408 is determined by VDD(P). At power on, the I/Os are configured as inputs; however, the system master can enable the I/Os as either inputs or outputs by writing to the I/O direction bits. The data for each input or output is kept in the corresponding Input or Output register. All registers can be read by the system master. The PI4IOE5V6408 has open -drain interrupt (INT) output pin that goes LOW when the input state of a GPIO -port changes from the input -state default register value. The device also has an interrupt masking feature by which the user can mask the interrupt from an individual GPIO -port.
