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)).
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 Latched outputs with 25 mA sink capability for directly driving LEDs 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.
