The PCA9548APW,112 from NXP Semiconductors is an octal bidirectional translating switch controlled via the I2C-bus. It features an upstream SCL/SDA pair that fans out to eight downstream pairs or channels, allowing for flexible channel selection through a programmable control register. This device supports voltage level translation between different bus voltages, such as 1.8 V, 2.5 V, 3.3 V, and 5 V, without additional protection, making it suitable for mixed-voltage systems.
Key electrical specifications include an operating supply voltage range of 2.3 V to 5.5 V, a maximum operating temperature of +85 °C, and a minimum operating temperature of -40 °C. The switch supports a clock frequency of up to 400 kHz and has an on-resistance of 24 Ohms. It also features 6 V tolerant inputs and ESD protection exceeding 2000 V HBM.
The PCA9548APW,112 is available in a 24-TSSOP package, designed for surface mount applications. It includes an active-low reset input for recovering from bus issues and supports hot insertion. The device is RoHS3 compliant, with an MSL of 1.
