PCA8574; PCA8574A  
Remote 8-bit I/O expander for I2C-bus with interrupt  
Rev. 3 — 3 June 2013  
Product data sheet  
1. General description  
The PCA8574/74A 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, 400 kHz I2C-bus interface, 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 PCA8574 and PCA8574A are identical, except for the different fixed portion of the  
slave address. The three hardware address pins allow eight of each device to be on the  
same I2C-bus, so there can be up to 16 of these I/O expanders PCA8574/74A together on  
the same I2C-bus, supporting up to 128 I/Os (for example, 128 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 I2C-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  
I2C-bus to parallel port expander  
400 kHz I2C-bus interface (Fast-mode I2C-bus)  
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  
Active LOW open-drain interrupt output  
Eight programmable slave addresses using three address pins  
Low standby current (4.5 A typical)  
40 C to +85 C operation
