The Texas Instruments PCA9544ARGYR is a versatile 4-channel I2C and SMBus multiplexer. It supports bidirectional translating switches and is compatible with I2C and SMBus protocols. This device features four active-low interrupt inputs and an active-low interrupt output, enhancing system control.
With three address pins, up to eight devices can be connected on the I2C bus. Channel selection is managed via the I2C bus. The PCA9544ARGYR allows for voltage-level translation between 1.8-V, 2.5-V, 3.3-V, and 5-V buses, making it suitable for mixed-voltage environments. It operates with a supply voltage range of 2.3V to 5.5V and features 5.5V tolerant inputs.
This multiplexer is available in a 20-VQFN package with surface mount mounting type. It supports clock frequencies up to 400 kHz and operates within an ambient temperature range of -40°C to 85°C. The device is designed for hot insertion and exhibits low standby current.
