PCA9674; PCA9674A

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

C-bus with interrupt

Rev. 7 — 30 May 2013

Product data sheet

1. General description

The PCA9674/74A provides general-purpose remote I/O expansion via the two-wire

bidirectional I

C-bus (serial clock (SCL), serial data (SDA)).

The devices consist of eight quasi-bidirectional ports, 1 MHz I

C-bus Fast-mode Plus

(Fm+) family interface, with high speed data transfer it can support PWM dimming of

LEDs, and higher I

C-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. The quasi-bidirectional port can be independently assigned as

an input to monitor interrupt status or keypads, or as an output to activate indicator

devices such as LEDs. The system master can read from the input port or write to the

output port through a single register.

The low current consumption of 4.5

A

(typical, static) is great for mobile applications and

the latched output ports have 25 mA high current sink drive capability for directly driving

LEDs.

The PCA9674 and PCA9674A are identical except for the different, non-overlapping slave

address. The three hardware selectable address pins can be decode to 64 addresses for

the PCA9674 and 62 addresses for the PCA9674A, so there can be up to 126 of these I/O

expanders PCA9674/74A together on the same I

C-bus without the need for bus buffers,

supporting up to 1008 I/Os (for example, 1008 LEDs).

The active LOW open-drain interrupt output (INT) can be connected to the interrupt logic

of the microcontroller and is activated when any input state differs from its corresponding

input port register state. It is used to indicate to the microcontroller that an input state has

changed and the device needs to be interrogated without the microcontroller continuously

polling the input register via the I

C-bus.

The internal Power-On Reset (POR) initializes the I/Os as inputs with a weak internal

pull-up 100

A

current source.

2. Features and benefits



C-bus to parallel port expander

1 MHz I

Operating supply voltage 2.3 V to 5.5 V with 5.5 V tolerant I/Os held to V

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
