Summary

Description
English: Two inputs are connected to open-collector buffers. If a buffer's input is high, the buffer will be in a high-impedance output state. If a buffer's input is low, the buffer will connect to ground. If all inputs are high, the output will be pulled high by the pull-up resistor. But if any input is low, the output will be pulled low by the buffer for that input. This corresponds to wired AND in active-high logic, or to wired OR in active-low logic, and allows multiple inputs to share the same output wire.
