The NXP Semiconductors PCA9549 is a multi-voltage bidirectional translating I2C bus controller. This CMOS component, designated as PCA9549PW, offers 8 bidirectional switches that connect two I2C buses. It supports I2C clock frequencies up to 400 kHz and operates over a supply voltage range of 2.3 V to 5.5 V. The PCA9549 series is suitable for applications in industrial automation, consumer electronics, and automotive systems where multiple I2C devices require independent bus access or voltage level translation. This device is supplied in a 24-lead TSSOP package with a 0.65 mm terminal pitch. Its operating temperature range is -40 °C to +85 °C.
