Low voltage 16-bit I2C-bus I/O port with interrupt and reset

The PCA9539A is a low-voltage 16-bit General Purpose Input/Output (GPIO) expanderwith interrupt and reset for I²C-bus/SMBus applications. 恩XP I/O expanders provide asimple solution when additional I/Os are needed while keeping interconnections to aminimum, for example, in ACPI power switches, sensor I²C-bus to parallel port expander\nPin and function compatible with PCA9539\nOperating power supply voltage range of 1.65 V to 5.5 V\nLow standby current consumption:1.5 μA (typical at 5 V VDD)\n1.0 μA (typical at 3.3 V VDD)\nSchmitt-trigger action allows slow input transition and better switching n;
