NCA95xx I2C GPIO Expanders

Nexperia NCA95xx I2C General-Purpose I/O (GPIO) Expanders provide an elegant solution when additional I/Os are needed while keeping the interconnections to a minimum. Housed in TSSOP24 and HWQFN24 packages, these GPIO expanders have multiple features like interrupts, hardware RESET, internal pull-up resistors, and configurable pull-ups. These Nexperia NCA95xx GPIO expanders feature benefits such as extremely low static power consumption and reduced PCB design complexity through trace reduction and routing simplification, thereby reducing the BOM cost.
