What are the key features of the TCA9534?

It features an open-drain interrupt output, 400kHz I2C bus support, 1.65V to 5.5V operating range, and configurable I/O ports.

How many devices can be connected to the same I2C bus?

Up to 8 devices can be connected to the same I2C bus using the three hardware address pins (A0, A1, A2).

What should be considered when using the interrupt output?

The INT pin is open-drain and requires an external pull-up resistor to VCC to function correctly.

What is the pinout of TCA9534PWR?

Use the TCA9534PWR datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about TCA9534PWR pinout to locate pins, power rails, and interface signals before layout.
