PCA9674/74A

Remote 8-bit I/O expander for Fm+ I

C-bus with interrupt

Rev. 05 — 15 June 2009

Product data sheet

1. General description

The PCA9674/74A provide general purpose remote I/O expansion for most

microcontroller families via the two-line bidirectional bus (I

C-bus) and is a part of the

Fast-mode Plus (Fm+) family.

The PCA9674/74A is a drop-in upgrade for the PCF8574/74A providing higher Fast-mode

Plus I

C-bus speeds (1 MHz versus 400 kHz) so that the output can support PWM

dimming of LEDs, higher I

C-bus drive (30 mA versus 3 mA) so that many more devices

can be on the bus without the need for bus buffers, higher total package sink capacity

(200 mA versus 100 mA) that supports having all LEDs on at the same time and more

device addresses (64 versus 8) are available to allow many more devices on the bus

without address conﬂicts.

The devices consist of an 8-bit quasi-bidirectional port and an I

C-bus interface. The

PCA9674/74A have low current consumption and include latched outputs with 25 mA high

current drive capability for directly driving LEDs.

They also possess an interrupt line (INT) that can be connected to the interrupt logic of

the microcontroller. By sending an interrupt signal on this line, the remote I/O can inform

the microcontroller if there is incoming data on its ports without having to communicate via

the I

C-bus.

The internal Power-On Reset (POR) or Software Reset sequence initializes the I/Os as

inputs.

2. Features

1 MHz I

C-bus interface

Compliant with the I

C-bus Fast and Standard modes

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

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

Active LOW open-drain interrupt output

64 programmable slave addresses using 3 address pins

Readable device ID (manufacturer, device type, and revision)

Low standby current

−40 °C

to +85

°C

operation

ESD protection exceeds 2000 V HBM per JESD22-A114, 200 V MM per

JESD22-A115, and 1000 V CDM per JESD22-C101
