The XRA1405IG24TR-F is a 16-bit GPIO expander featuring an SPI interface, designed for applications requiring additional I/O capabilities. It operates within a voltage range of 1.65V to 3.6V and supports a maximum SPI clock frequency of 26MHz. Each of the 16 GPIOs can be individually configured as inputs or outputs, with options for enabling internal pull-up resistors and polarity inversion. The device also includes programmable interrupt capabilities, allowing interrupts to be triggered on rising, falling, or both edges. The XRA1405IG24TR-F is housed in a 24-pin QFN package, which is suitable for space-constrained designs. It offers 5V tolerant inputs and features integrated level shifters, making it compatible with various voltage levels. The device has a low standby current of 1µA at 1.8V and provides robust ESD protection of 3kV HBM. This expander is ideal for use in battery-operated devices, personal digital assistants, cellular phones, and other applications where additional GPIOs are needed.
