The PCA9546A is a 4-channel I2C bus multiplexer designed for bidirectional switching, allowing communication between different I2C bus voltages ranging from 1.8V to 5V. It features a programmable control register that enables the selection of any individual channel or combination of channels. The device includes an active LOW reset input to recover from situations where a downstream bus may be stuck in a LOW state, ensuring reliable operation. With a supply voltage range of 2.3V to 5.5V, the PCA9546A supports clock frequencies up to 400 kHz and is compatible with SMBus standards. The device is packaged in a SOIC-16 format and is RoHS compliant. It also offers low on-resistance switches, low standby current, and ESD protection exceeding 2000V HBM. This multiplexer is suitable for applications requiring voltage level translation and multiple I2C devices on a single bus.
