NXP USA Inc. PCA8574D-512 is an I/O expander featuring an 8-bit, open-drain output configuration. This device interfaces via the I2C bus with a maximum clock frequency of 400 kHz. Each I/O pin can source up to 25mA or sink 100µA, and the outputs are push-pull. The PCA8574D-512 includes an interrupt output feature, configurable as active-high or active-low, and a power-on reset (POR) circuit. It operates over a supply voltage range of 2.3V to 5.5V and is housed in a 16-SOIC package suitable for surface mounting. This component is commonly utilized in consumer electronics, industrial control systems, and automotive applications requiring flexible I/O expansion. The operating temperature range is -40°C to 85°C.
