NCA9555 - Low-voltage 16-bit I2C and SMBus I/O expander
The NCA9555 provides 16 bits of General Purpose Input/Output (GPIO) expansion for I²C-bus/SMBus applications.
It is designed for a wide voltage range of 1.65 V to 5.5 V with interrupt and default pull-up resistors on GPIOs.
Nexperia GPIO expanders provide an elegant solution when additional IOs are
NCA9555 Features
* 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 inp
