The PCA9543APW,112 from NXP Semiconductors is a bidirectional translating switch controlled by the I2C-bus. It features a 1-of-2 channel configuration, allowing the upstream I2C-bus pair to fan out to two downstream pairs. This device is compatible with SMBus standards and supports a clock frequency up to 400 kHz.
Key electrical specifications include an operating supply voltage range of 2.3V to 5.5V, an on-resistance of 30 Ohms, and a propagation delay time of 0.3 ns. It also offers active LOW interrupt inputs and an active LOW reset input for robust control.
The PCA9543APW,112 is supplied in a 14-TSSOP package with surface mount mounting type. The package dimensions are 8.75 mm in length, 4 mm in width, and 1.45 mm in height. It operates within a temperature range of -40 C to 85 C.
This I2C switch is suitable for applications requiring voltage level translation between different bus voltages, such as 1.8 V, 2.5 V, 3.3 V, and 5 V parts, without additional protection.
