The NCA9539 provides 16 bits of General Purpose Input/Output (GPIO) expansion 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:.
2.5 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.
Open-drain a.
