The PCA9547PW,112 from NXP Semiconductors is an octal bidirectional translating multiplexer designed for I2C-bus applications. It features 8 downstream channels that fan out from a single upstream SCL/SDA pair, allowing for selective communication with devices on different buses. The device operates with a supply voltage range of 2.3 V to 5.5 V and supports I2C clock frequencies up to 400 kHz.
This multiplexer facilitates voltage level translation, enabling communication between buses operating at different voltage levels such as 1.8 V, 2.5 V, 3.3 V, and 5 V. All I/O pins are 5 V tolerant. It includes an active LOW reset input for bus recovery and 3 address pins, allowing up to 8 devices on the I2C-bus. The device powers up with Channel 0 connected, providing immediate master communication.
The PCA9547PW,112 is available in a 24-TSSOP surface-mount package. Its design supports hot insertion and features low Ron multiplexers and low standby current. ESD protection exceeds 2000 V HBM and 1000 V CDM, with latch-up testing exceeding 100 mA.
