Features & Applications

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.

Features:

400 kHz I2C-bus interface
2.3 V to 5.5 V operation with 5.5 V tolerant I/Os
16-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 400 mA
Active LOW open-drain interrupt output
8 programmable slave addresses using 3 address pins
Readable device ID (manufacturer, device type, and revision)
Low standby current (10 mA max.)

Applications:

LED signs and displays
Servers
Industrial control
Medical equipment
PLCs
Cellular telephones
