Description
technical field [0001] Embodiments of the present invention relate to latch circuit technology, in particular to a fault signal latch circuit. Background technique [0002] The fault hardware latch circuit is a circuit that detects and maintains the fault signal when the system fails, which can prevent the fault from being detected due to the disappearance of the input low-level fault signal, or the fault signal is at a high or low level. The frequent jumps between them make the fault state of the system switch frequently and cause the system to enter a disordered state. [0003] In the prior art, the fault latching circuit uses the method of AND gate and OR gate to complete the fault latching, and has the function of fault clearing. However, due to the use of two different gate circuits, at least two chips are required to complete the function in actual use, increasing the system complexity and cost. Contents of the invention [0004] The invention provides a fault sign...
