A wired OR circuit can be configured by using a buffer with an open-drain output (74HC07, etc.). (Fig. 1)
It is also possible to configure wired-OR with products with 3-state output buffers (74VHC126, etc.). The A and B terminals can be fixed to low (L), and wired OR can be configured using the G1 and G2 terminals and an external pull-up resistor.
