The PCA9547PW,118 from NXP Semiconductors is an octal bidirectional translating multiplexer designed for I2C-bus control. It features a single upstream SCL/SDA pair that fans out to eight downstream pairs, allowing selection of one channel at a time via the I2C-bus. The device powers up with Channel 0 connected, enabling immediate communication.
Key electrical specifications include an operating power supply voltage range of 2.3 V to 5.5 V and a maximum clock frequency of 400 kHz. The inputs are 5 V tolerant, and the multiplexer allows for voltage level translation between different bus voltages such as 1.8 V, 2.5 V, 3.3 V, and 5 V. It also includes an active LOW reset input for recovering from bus lock-ups.
This component is supplied in a 24-TSSOP package, suitable for surface mount applications. It offers robust ESD protection exceeding 2000 V HBM and 1000 V CDM, and latch-up testing exceeds 100 mA.
The PCA9547PW,118 is compatible with SMBus standards and supports hot insertion, making it a versatile solution for complex I2C systems requiring channel expansion or voltage level interfacing.
