PCA9674A - Remote 8-bit I/O expander

Download the PCA9674A datasheet PDF. This datasheet also covers the PCA9674 variant, as both devices belong to the same remote 8-bit i/o expander family and are provided as variant models within a single manufacturer datasheet.

General Description

The PCA9674/74A provides general-purpose remote I/O expansion via the two-wire bidirectional I2C-bus (serial clock (SCL), serial data (SDA)).

Key Features

  • I2C-bus to parallel port expander.
  • 1 MHz I2C-bus interface (Fast-mode Plus I2C-bus).
  • SDA with 30 mA sink capability for 4000 pF buses.
  • Operating supply voltage 2.3 V to 5.5 V with 5.5 V tolerant I/Os held to VDD with 100 A current source.
  • 8-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 200 mA NXP Semiconductors PCA9674; PCA9674A Remote 8-bit I/O.

uct data sheet 1. General description The PCA9674/74A provides general-purpose remote I/O expansion via the two-wire bidirectional I2C-bus (serial clock (SCL), serial data (SDA)). The devices consist of eight quasi-bidirectional ports, 1 MHz I2C-bus Fast-mode Plus (Fm+) family interface, with high speed data transfer it can support PWM dimming of LEDs, and higher I2C-bus drive 30 mA for more devices can be on the bus without the need for bus buffers. Three hardware address inputs and interrupt output operating between 2.3 V and 5.5 V.
