PCA9703 18V Tolerant SPI GPI Shift Registers

NXP Semiconductors PCA9703 18V Tolerant SPI 16-bit GPI Shift Registers are designed to monitor the status of switch inputs, and the series can monitor up to 16 switch inputs. These registers generate an interrupt when one or more of the switch inputs change state, but allow selected inputs to not generate interrupts using the interrupt masking feature. NXP Semiconductors PCA9703 18V Tolerant SPI 16-bit GPI Shift Registers are ideal for a variety of applications, including automotive, industrial equipment, cell phones, and emergency lighting.
