Additional preview pages of the PCA9555 datasheet.

The PCA9555 provides 16 bits of General Purpose Input/Output (GPIO) expansion for I²C-bus/SMBus applications.

It is designed for a wide voltage range of 2.3 V to 5.5 V with interrupt and default pull-up resistors on GPIOs.

I²C-bus to parallel port expander.
Operating power supply voltage range of 2.3 V to 5.5 V.
Ultra low standby current consumption:.
1 µA (maximum).
Schmitt-trigger action allows slow input transition and better switching noise immunity at the SCL and SDA inputs.
Vhys = 0.10 × VCC (typical).
Noise filter on SCL and SDA inputs.
5 V tolerant I/Os.
16 I/O pins which power up configured in input state with weak pull-up r.
