The Texas Instruments PCF8574PWG4 is an 8-bit I/O expander designed for efficient interfacing with microcontrollers via the I2C bus. Operating at clock frequencies up to 100 kHz, this component offers a versatile solution for increasing available I/O pins in embedded systems. Its push-pull output type supports source currents up to 1mA and sink currents up to 25mA. The device features a Power-On Reset (POR) function and provides an interrupt output for event-driven notifications. With a supply voltage range of 2.5V to 6V and an operating temperature range of -40°C to 85°C, the PCF8574PWG4 is suitable for applications in consumer electronics, industrial automation, and telecommunications. The component is housed in a 20-TSSOP package, enabling surface mount integration.
