NCA/PCA Series Expanders

Nexperia NCA and PCA series expanders offer a range of low-voltage 16-bit I²C and SMBus I/O expanders designed to provide additional general-purpose input/output (GPIO) capabilities for various applications. These devices are engineered for a wide voltage range of 1.65 V to 5.5 V. They feature interrupt outputs, configuration registers, and programmable pull-up resistors, making them ideal for automotive and industrial environments. The automotive-qualified variants (denoted by the "-Q100" suffix) meet AEC-Q100 standards, ensuring high reliability and robustness. These I/O expanders are available in compact TSSOP and HWQFN packages, providing a space-saving solution for modern electronic designs. With their advanced features and reliable performance, the NCA and PCA series devices simplify circuit design, reduce component count, and enhance system functionality.
