PCA8574/74A  
Remote 8-bit I/O expander for I2C-bus with interrupt  
Rev. 02 — 14 May 2007  
Product data sheet  
1. General description  
The PCA8574/74A provide general purpose remote I/O expansion for most  
microcontroller families via the two-line bidirectional I2C-bus (serial clock (SCL), serial  
data (SDA)).  
The devices consist of an 8-bit quasi-bidirectional port and an I2C-bus interface. The  
PCA8574/74A have low current consumption and include latched outputs with 25 mA high  
current drive capability for directly driving LEDs.  
The PCA8574/74A 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) initializes the I/Os as inputs.  
2. Features  
I 400 kHz I2C-bus interface  
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 8 programmable slave addresses using 3 address pins  
I Readable device ID (manufacturer, device type, and revision)  
I Low standby current (10 µA max.)  
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  
I Latch-up testing is done to JEDEC standard JESD78 which exceeds 100 mA  
I Packages offered: DIP16, SO16, TSSOP16, SSOP20  
3. Applications  
I LED signs and displays  
I Servers  
I Industrial control  
I Medical equipment  
I PLCs
