PI4MSD5V9548AZDEX

The PI4MSD5V9548AZDEX is an industry-standard, low-voltage 8-channel I2C-bus multiplexer from Diodes Incorporated. This device is designed to enable the expansion of multiple I2C devices or channels to be controlled by a single I2C bus. It operates within a voltage range typically from 1.65V to 5.5V, making it suitable for a variety of applications that require low power consumption and versatile interfacing capabilities.
The multiplexer features 8 bidirectional translating switches, allowing one I2C master to communicate with multiple I2C slave devices without conflict. Each channel can be individually enabled or disabled, providing flexibility in system design. It supports clock stretching, arbitration, and high-speed I2C-bus frequencies up to 400 kHz.
The device comes in a compact package, suitable for space-constrained applications, and is commonly used in consumer electronics, computing, automotive, and industrial systems to enhance connectivity and manage multiple peripheral devices efficiently. The PI4MSD5V9548AZDEX helps simplify complex I2C-bus designs by reducing the need for additional wiring and circuitry.
