Description
General part information
PCA9534A Series
The PCA9534A and PCA9534 are identical, except for their fixed I2C address. This allows for up to 16 of these devices (8 of each) on the same I2C bus.
INTcan be connected to the interrupt input of a 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. Thus, the PCA9534A can remain a simple slave device.
The device’s outputs (latched) have high-current drive capability for directly driving LEDs. It has low current consumption.
