The Texas Instruments PCA9534DBR is an 8-bit I/O expander designed for I2C and SMBus communication. It operates within a voltage range of 2.3V to 5.5V and supports a maximum clock frequency of 400 kHz. This device features an open-drain, active-low interrupt output, allowing for efficient system signaling.
Key specifications include 8 I/O pins, configurable via internal registers. The PCA9534DBR supports 5V tolerant I/O ports and has a low standby current consumption. It is available in a 16-SSOP package, suitable for surface mount applications.
This I/O expander is useful for adding general-purpose I/O to microcontrollers where pin count is limited. Its features like configuration registers and interrupt pin make it a versatile component for various embedded systems. The device also includes features like internal power-on reset and noise filters on SCL/SDA inputs.
