9 / 32 page ![]() UM0162 1 Hardware 9/32 1.3 Output connections Figure 8 describes the CANIC10 output structure and its connections for supporting VN340 and VN808 Reference Design Boards. 74HC541 Octal Bus Buffers (U5, U9 and U13) with 3-state outputs are used to force microcontroller outputs. The buffer outputs are permanently selected (by pins G1 and G2) and connected directly to the output connectors (J12, J31, J46 and J53). These connectors can be also used to supply the CANIC10 system (in compliance with J8, J10, J30, J28, J47, J48, J51 and J52 settings). Figure 8.
