The 74HC245 Octal Bus Transceiver is a logic IC in the LabWired part catalog. Its catalog type is 74hc245. It connects to the MCU over GPIO. The catalog gives a supply range of 2–6 V. It has 20 pins. A registered peripheral model runs in the engine: the firmware talks to it over the real bus and gets device-accurate responses.
From the catalog: Octal bus transceiver, DIR + one part-wide OE (core/configs/devices/74hc245.yaml), 11 ns. All eight bits switch together; there is no per-bit enable.
