TCA9544APWR TI Signal Switches, Multiplexers, Decoders
The TCA9544A is a 4-channel I2C bus switch with interrupt outputs and active-low reset, operating from a 2.3 V to 5.5 V supply. It allows any combination of 4 downstream I2C buses to be connected to a single upstream bus, enabling selection of one channel at a time. The device includes an interrupt logic that flags downstream interrupts to the upstream master. Packaged in a 20-pin TSSOP (PW), it is ideal for I2C bus expansion and isolation in servers, telecom equipment, and industrial control systems.
