The Texas Instruments PCA9555DBR is a 16-bit I/O expander designed for I2C and SMBus interfaces. 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 interrupt output and is available in a 24-SSOP package, suitable for surface mounting.
With 16 I/O pins, the PCA9555DBR offers flexibility for expanding digital input/output capabilities in embedded systems. The expander supports push-pull output types and operates across a temperature range of -40°C to 85°C. It is designed for applications requiring additional GPIOs where microcontroller pins are limited.
The PCA9555DBR is specified with current capabilities of 10mA and 25mA. It includes features like Power-On Reset (POR). The component is packaged in a 24-SSOP (0.209", 5.30mm Width) for surface mount applications.
