Low-voltage 8-bit I2C-bus and SMBus low power I/O port with interrupt, reset and Agile I/O

The PCAL9538A is a low-voltage 8-bit General Purpose Input/Output (GPIO) expander with interrupt and reset for I²C-bus/SMBus applications. NXP® I/O expanders provide simple solutions when additional I/Os are needed while keeping interconnections to a minimum, for example, in ACPI power switches, sen • I²C-bus to parallel port expander\n• Operating power supply voltage range of 1.65 V to 5.5 V\n• Low standby current consumption• 1.5 μA (typical at 5 V VDD)\n• 1.0 μA (typical at 3.3 V VDD)\n• Schmitt-trigger action allows slow input transition and better switching noise immunity at the SCL and SD;
