The Texas Instruments PCA9543APW is a dual bidirectional translating switch controlled by the I2C bus. The SCL/SDA upstream pair fans out to two downstream pairs, or channels. This device is suitable for voltage-level translation between 1.8-V, 2.5-V, 3.3-V, and 5-V buses.
Key electrical specifications include an operating power-supply voltage range of 2.3 V to 5.5 V and a clock frequency of up to 400 kHz. The inputs are tolerant to 5.5V. It features two active-low interrupt inputs and an active-low reset input, along with two address pins allowing up to four PCA9543A devices on the I2C bus.
Packaged in a 14-TSSOP, the PCA9543APW is designed for surface mount applications. It supports hot insertion and has no glitch on power-up. The part is obsolete and no longer in production, with PCA9543APWR listed as an alternate with upgraded functionality.
