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

General description The PCA9555A is a low-voltage 16-bit General Purpose Input/Output (GPIO) expander with interrupt and weak pull-up resistors for I2C-bus/SMBus applications. NXP I/O expanders provide a simple solution when additional I/Os are needed while keeping interconnections to a minimum

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

The PCA9555A is a low-voltage 16-bit General Purpose Input/Output (GPIO) expanderwith interrupt and weak pull-up resistors for I²C-bus/SMBus applications. NXP I/Oexpanders provide a simple solution when additional I/Os are needed while keepinginterconnections to a minimum, for example, in ACPI power I²C-bus to parallel port expander\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 noise immunityat the SCL and SDA inputs:Vhy;
