NCA9539 - Low-voltage 16-bit I2C and SMBus low-power I/O expander
The NCA9539 provides 16 bits of General Purpose Input/Output (GPIO) expansion with interrupt and reset for I²C-bus/SMBus applications.
It is designed for a wide voltage range of 1.65 V to 5.5 V.
Nexperia GPIO expanders provide an elegant solution when additional IOs are needed while keeping the inte
NCA9539 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
