PCA9671D - Remote 16-bit I/O expander

Download the PCA9671D datasheet PDF. This datasheet also covers the PCA9671 variant, as both devices belong to the same remote 16-bit i/o expander family and are provided as variant models within a single manufacturer datasheet.

General Description

The PCA9671 provides general purpose remote I/O expansion for most microcontroller families via the two-line bidirectional bus (I2C-bus) and is a part of the Fast-mode Plus (Fm+) family.

Key Features

  • 1 MHz I2C-bus interface.
  • Compliant with the I2C-bus Fast-mode and Standard-mode.
  • SDA with 30 mA sink capability for 4000 pF buses.
  • 2.3 V to 5.5 V operation with 5.5 V tolerant I/Os.
  • 16-bit remote I/O pins that default to inputs at power-up.
  • Latched outputs with 25 mA sink capability for directly driving LEDs.
  • Total package sink capability of 400 mA.
  • Active LOW reset input.
  • 64 programmable slave addresses using 3 address pins.
  • Readable device ID.
