Simplify IC expansion and address conflicts with the7SEMI TCA9544A IC MUX Board. This4-channel bidirectional IC/SMBus multiplexersupports seamless switching between multiple slave devices and offers advancedinterrupt logic,reset functionality, andvoltage-level translation.
Based on the reliable TI TCA9544A IC, the board enables a single IC master to communicate with up tofour downstream IC buses, each with its own interrupt line (INT0INT3). This is especially useful in projects involvingidentical sensor devices,data acquisition systems, orindustrial I/O multiplexing.
