Abstract

The invention relates to a method for arranging ports of circuit modules to prevent short-circuit out of control, which can simply solve the technical problem of out-of-control caused by short-circuit between core module ports (pins) of the anti-out of control circuit. Module (IC) port positions are arranged in a safe arrangement. Although the method is simple, it has a particularly good effect in preventing the short-circuit between adjacent ports (pins) from getting out of control, and further improves the function and performance of the core circuit module (IC) to prevent run-away, so that the system circuit has a comprehensive run-off-control capability. Therefore, the present invention has important practical value.

Description

technical field [0001] The invention relates to a method for arranging and arranging ports of a circuit module (IC), in particular to a method for arranging ports of a circuit module (IC) for preventing short-circuit out of control. This method can prevent the out-of-control caused by the short-circuit fault between the adjacent ports of the core module of the relevant circuit (the executive circuit is not controlled by the logic state or does not control the load according to the logic requirement, which is called out-of-control / failure). Although the invention is simple, the effect of preventing short circuit out of control is particularly good, and has important practical value. Background technique [0002] Previously, the name of the utility model patent that I invented was bottom anti-control time base circuit (patent number is 201020211450.2) and the temperature control or timing circuit related to preventing abnormal failure out of control. , It can also prevent the...
