Introduction

AI Translation

The PCF8574 is primarily used for GPIO port expansion. Port data is transmitted via the standard two-wire I²C protocol. The PCF8574 features 8-bit quasi-bidirectional GPIO ports (P0–P7) capable of directly driving LEDs. Each quasi-bidirectional GPIO port can be used as either input or output without requiring a data direction control signal. Upon power-up, all GPIO ports default to a high level.
