The SIT1044TK/3 is a universal bus function IC with DFN-8 (3x3) package and RoHS compliant design. The IC is based on the Analog Bus Interface (ABI) principle and is designed to be used in various applications that require interface between two or more buses, such as in data communication systems, multimedia systems, industrial automation systems, and consumer electronics. It features two serialized input/output (TX/RX) channels, an address bus, an eight-bit memory mapped I/O, enhanced memory protections, and several digital signal operation modes. In addition, the device supports multi-level addresses, mask interrupts, programmable pull-up resistors, and programmable powerdown. Furthermore, the IC has advanced power management, low power operation, and is compatible with a wide range of bus voltage levels.
