Low-voltage 16-bit I2C-bus I/O port with interrupt and weak pull-up

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. Nexperia GPIO expanders provide an elegant solution when additional IOs a; ? I2C-bus to parallel port expander\n? Operating power supply voltage range of 2.3 V to 5.5 V\n? Ultra low standby current consumption:? 1 μA (maximum)\n\n? Schmitt-trigger action allows slow input transition and better switching noise immunity at the SCL and SDA inputs? Vhys = 0.10 × VCC (typical)\;
