Product details

Description

The PCA9673 provides general purpose remote I/O expansion for most microcontroller families via the two-line bidirectional bus (I2C-bus) and is a part of the Fast-mode Plus family.

Features

1 MHz I2C-bus interface.
Compliant with the I2C-bus Fast and Standard modes.
SDA with 30 mA sink capability for 4000 pF buses.
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.
16 programmable slave addresses using 2 address pins.
Readabl.
