PCA9555A, Low-voltage 16-bit I2C-bus I/O port
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, for example, in ACPI po
PCA9555A Features
* I2C-bus to parallel port expander
* Operating power supply voltage range of 1.65 V to 5.5 V
* Low standby current consumption:
* 1.5 A (typical at 5 V VDD)
* 1.0 A (typical at 3.3 V VDD)
* Schmitt-trigger action allows slow input transition and better switching noise immu
