Additional preview pages of the PCAL9539A datasheet.

The PCAL9539A is a low-voltage 16-bit General Purpose Input/Output (GPIO) expander with interrupt and reset for I2C-bus/SMBus applications.

I2C-bus to parallel port expander.
Operating power supply voltage range of 1.65 V to 5.5 V.
Low standby current consumption:.
1.5 A (typical at 5 V VDD).
1.0 A (typical at 3.3 V VDD).
Schmitt-trigger action allows slow input transition and better switching noise immunity at the SCL and SDA inputs.
Vhys = 0.10  VDD (typical).
5 V tolerant I/Os.
Active LOW reset input (RESET).
Open-drain active LOW interrupt output (INT).
400 kHz Fast-mode.
