Low-voltage 8-bit I2C-bus I/O port with interrupt and reset

The PCA9538A is a low-voltage 8-bit General Purpose Input/Output (GPIO) expanderwith interrupt and reset for I²C-bus/SMBus applications. NXP I/O expanders provide asimple solution when additional I/Os are needed while keeping interconnections to aminimum, for example, in ACPI power switches, sensors 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 inputsVhys;

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

The PCA9538 is a 16-pin CMOS device that provides 8 bits of General Purpose parallel Input/Output (GPIO) expansion with interrupt and reset for I2C-bus/SMBus applications and was developed to enhance the NXP Semiconductors family of II2CC-bus I/O expanders. I/O expanders provide a simple solution wh • 8-bit I²C-bus GPIO with interrupt and reset\n• Operating power supply voltage range of 2.3 V to 5.5 V (3.0 V to 5.5 Vfor PCA9538PW/Q900)\n• 5 V tolerant I/Os\n• Polarity Inversion register\n• Active LOW interrupt output\n• Active LOW reset input\n• Low standby current\n• Noise filter on SCL/SDA in;
