Bidirectional bus repeater

The invention relates to a bidirectional bus repeater. The invention also relates to a communication bus comprising such a bidirectional bus repeater, and to a communication system comprising such a communication bus. According to the invention, the bidirectional bus repeater comprises a first input terminal, a second input terminal, a first pull-down element connected to the first input terminal and a second pull-down element connected to the second input terminal. By ensuring that the activation of the first pull-down element and the second pull-down element depends on the state of the respective input terminal and the detection of the high-to-low transition of the respective other input terminal, a self-locking problem can be avoided or at least minimized. 本发明涉及一种双向总线中继器。本发明还涉及包括这种双向总线中继器的通信总线，以及包括这种通信总线的通信系统。根据本发明，所述双向总线中继器包括第一输入端子、第二输入端子、连接到所述第一输入端子的第一下拉元件和连接到所述第二输入端子的第二下拉元件。通过确保所述第一下拉元件和所述第二下拉元件的激活取决于相应输入端子的状态和相应的另一输入端子的高到低转换的检测，可以避免自锁问题或至少使该问题最小化。
