PCA9703 Datasheet 16-bit Gpi

Manufacturer: NXP Semiconductors

Overview: 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

Key Features

  • 16 general purpose input ports.
  • 18 V tolerant input ports with 100 k external series resistor.
  • Input LOW threshold 0.55  VDD with minimum of 2.5 V at VDD = 4.5 V.
  • Open-drain interrupt output.
  • Interrupt enable pin (INT_EN) disables GPI pins and interrupt output.
  • Interrupt-masking feature allows no interrupt generation from selected inputs.
  • VDD range: 4.5 V to 5.5 V.
  • IDD is very low 2.5 A maximum.
  • SPI serial interface with speeds up to 5 MHz.
  • S.
