The output is push-pull, totem pole, which means it drives both high and low without requiring an external pull-up resistor. That saves a component and a trace on the board. If your design expects an open-drain output for wired-OR sharing, this part will not work there — the push-pull stage fights any other driver. For a dedicated reset line to a single processor, it is the cleaner option.
