The Texas Instruments PCA9544ADGVR is a versatile 4-channel I2C and SMBus multiplexer designed for interface expansion and voltage translation. It operates within a supply voltage range of 2.3V to 5.5V, making it suitable for a wide array of applications.
This device features four active-low interrupt inputs and an active-low interrupt output, aiding in system monitoring and control. The PCA9544ADGVR allows for voltage-level translation between common bus voltages including 1.8V, 2.5V, 3.3V, and 5V. It is compatible with I2C and SMBus protocols and supports clock frequencies up to 400 kHz.
Packaged in a 20-TVSOP, the PCA9544ADGVR is designed for surface mounting. Its features include low ON-resistance switches, no glitch on power-up, and support for hot insertion. The device also offers 5.5V tolerant inputs and robust ESD protection exceeding JESD 22 standards.
With three address pins, up to eight devices can be connected on the I2C bus, offering flexibility in system design. The PCA9544ADGVR is an effective solution for expanding I2C bus capacity and managing different voltage domains within a system.
