The PCA9547D,112 is an octal bidirectional translating multiplexer controlled by the I2C-bus, manufactured by NXP Semiconductors. It fans out an upstream SCL/SDA pair to eight downstream pairs, allowing selection of one channel at a time via the programmable control register. The device powers up with Channel 0 connected, enabling immediate communication.
Key features include an active LOW reset input for bus recovery, 3 address pins for up to 8 devices on the I2C-bus, and low ON-resistance multiplexers. It supports voltage level translation between 1.8 V, 2.5 V, 3.3 V, and 5 V buses, with all I/O pins being 5 V tolerant. The operating power supply voltage range is 2.3 V to 5.5 V, and it supports clock frequencies from 0 Hz to 400 kHz.
This component is supplied in a 24-SOIC surface mount package. ESD protection exceeds 2000 V HBM and 1000 V CDM, with latch-up testing exceeding 100 mA per JESD78.
The PCA9547D,112 is suitable for applications requiring multiplexing and voltage level translation within I2C and SMBus systems.
