The PCA9534ADBR is an 8-bit I2C and SMBus low-power I/O expander designed for operation within a voltage range of 2.3 V to 5.5 V. It features a low standby current consumption of 1 OºA maximum and supports a 400-kHz fast I2C bus. The device includes an open-drain active-low interrupt output, which signals the system master when any input state changes. It allows for up to eight devices to be connected on the same I2C bus using three hardware address pins (A0, A1, A2), and can be combined with the PCA9534 to support up to 16 devices. The PCA9534ADBR provides input and output configuration registers, a polarity inversion register, and an internal power-on reset feature that initializes the device with all channels configured as inputs. The outputs are latched and capable of driving high-current loads, such as LEDs. The device is also designed to prevent glitches on power-up and includes noise filtering on the SCL and SDA inputs. ESD protection exceeds industry standards, ensuring reliability in various applications. The PCA9534ADBR is available in a 16-pin SSOP package and operates within a temperature range of -40¬8C to 85¬8C.
