PCA9703 - 16-bit GPI

Description

The PCA9703 is a low power 18 V tolerant SPI General Purpose Input (GPI) shift register designed to monitor the status of switch inputs.

Features

  • 16 general purpose input ports.
  • 18 V tolerant input ports with 100 k external series resistor.

PCA9703 18 V tolerant SPI 16-bit GPI with maskable INT Rev. 4 — 5 September 2014 Product data sheet 1. General description The PCA9703 is a low power 18 V tolerant SPI General Purpose Input (GPI) shift register designed to monitor the status of switch inputs. It generates an interrupt when one or more of the switch inputs change state but allows selected inputs to not generate interrupts using the interrupt masking feature. The input level is recognized as a HIGH when it is greater than 0.8  VDD and as a LOW when it is less than 0.55  VDD (minimum LOW threshold of 2.5 V at 5 V node). The PCA9703 can monitor up to 16 switch inputs. The falling edge of the CS pin samples the input port status and clears the interrupt.
