DIODES Incorporated Signal Switches, Multiplexers, Decoders PI4MSD5V9546ALEX

The PI4MSD5V9546ALEX is a quad bidirectional translating multiplexer designed for I2C bus applications. It operates with a power supply voltage range of 1.65 V to 5.5 V and supports voltage level translation between various bus voltages, including 1.2V, 1.8V, 2.5V, 3.3V, and 5V. The device features low standby current and low on-resistance switches, ensuring efficient operation. Channel selection is managed via the I2C bus, allowing for flexible configuration of the four downstream channels. An active LOW reset input enables recovery from low-state conditions on downstream buses, while the internal Power-On Reset function ensures all channels are deselected upon power-up. The device is designed to support hot insertion and is equipped with ESD protection exceeding 8000 V HBM. The PI4MSD5V9546ALEX is available in multiple package options, including TSSOP-16L, making it suitable for various applications requiring reliable signal switching and multiplexing capabilities.
