PCA9674/74A  
Remote 8-bit I/O expander for Fm+ I2C-bus with interrupt  
Rev. 02 — 12 October 2006  
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 (I2C-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 I2C-bus speeds (1 MHz versus 400 kHz) so that the output can support PWM  
dimming of LEDs, higher I2C-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 I2C-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 I2C-bus.  
The internal Power-On Reset (POR) or Software Reset sequence initializes the I/Os as  
inputs.  
2. Features  
I 1 MHz I2C-bus interface  
I Compliant with the I2C-bus Fast and Standard modes  
I SDA with 30 mA sink capability for 4000 pF buses  
I 2.3 V to 5.5 V operation with 5.5 V tolerant I/Os  
I 8-bit remote I/O pins that default to inputs at power-up  
I Latched outputs with 25 mA sink capability for directly driving LEDs  
I Total package sink capability of 200 mA  
I Active LOW open-drain interrupt output  
I 64 programmable slave addresses using 3 address pins  
I Readable device ID (manufacturer, device type, and revision)  
I Low standby current  
I −40 °C to +85 °C operation  
I ESD protection exceeds 2000 V HBM per JESD22-A114, 200 V MM per  
JESD22-A115, and 1000 V CDM per JESD22-C101
