The PCA6408AHKX is an 8-bit I¬=C-bus and SMBus I/O expander designed for remote I/O expansion in various microcontroller applications. It operates within a voltage range of 1.65V to 5.5V, allowing for bidirectional voltage-level translation between different I/O voltage levels, which is particularly useful in mixed-signal environments. The device features a built-in level shifting capability, making it suitable for interfacing with peripherals operating at higher voltage levels. This I/O expander includes a configuration register for input/output selection, an interrupt output for state changes, and a reset function to restore default settings. It supports a fast-mode I¬=C-bus operation at speeds up to 400 kHz and has low standby current consumption of 1 ¬µA. The PCA6408AHKX is packaged in a compact XQFN16 format, making it suitable for space-constrained applications. Additionally, it provides ESD protection and can drive loads such as LEDs with a maximum output current of 25 mA. This product is ideal for applications requiring additional GPIOs while minimizing interconnections, such as in battery-powered devices.
