Nexperia 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 reduce the PCB design complexity through trace reduction and routing simplification, thereby reducing the BOM cost.

Features

Single supply GPIO expander supporting operating power supply voltage range of 1.65V to 5.5V operation
Serial to parallel (SDA to P0-P16) and parallel to serial (P0-P16) conversion with I²C protocol
Schmitt-trigger action allows slow input transition and better switching noise immunity at the SCL and SDA inputs
Low power consumption of 2.5µA maximum
400kHz operation (FM I²C mode)
Glitch-free power-up with all channels configured as inputs with weak pull-up resistors

5V tolerant I/Os and 16 I/Os pins, which defaults to 16 inputs
Latched outputs with 25mA drive maximum capability for directly driving LEDs
Polarity inversion register
External RESET pin to reset state machine and internal registers
Noise filters on SCL and SDA inputs
TSSOP24 and HWQFN24 packages
Specified from -40°C to +85°C and -40°C to +125°C
