PCA8575
Remote 16-bit I/O expander for I2C-bus with interrupt
Rev. 02 — 21 March 2007
Product data sheet
1. General description
The PCA8575 provides general purpose remote I/O expansion for most microcontroller
families via the two-line bidirectional I2C-bus (serial clock (SCL), serial data (SDA)).
The device consists of a 16-bit quasi-bidirectional port and an I2C-bus interface. The
PCA8575 has a low current consumption and includes latched outputs with high current
drive capability for directly driving LEDs.
The PCA8575 also possesses an interrupt line (INT) which 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 16-bit remote I/O pins that default to inputs at power-up

I Total package sink capability of 400 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: SO24, SSOP24 (QSOP24), TSSOP24, HVQFN24, DHVQFN24
3. Applications
