A selection circuit and electronic equipment

Abstract

The invention discloses a selection circuit and electronic equipment, which include: N selection modules, N control terminals, and gate terminals corresponding to each selection module one by one; wherein, N is an integer greater than or equal to 3; for For each selection module, only one of the N control terminals is its corresponding first control terminal, and at least two of the remaining control terminals are its corresponding second control terminals; and different selection modules The corresponding first control terminal is different, and the combination of the second control terminal corresponding to different selection modules is different; because each selection module not only makes the gate terminal corresponding to the selection module be selected when its corresponding first control terminal receives the opening signal and even when the first control terminal corresponding to the selection module is broken, the gate terminal corresponding to the selection module can be strobed when each second control terminal corresponding to it receives an opening signal, thereby achieve the same functionality.

Description

technical field [0001] The invention relates to the technical field of circuits, in particular to a selection circuit and electronic equipment. Background technique [0002] With the development of the electronic industry, various electronic products have become an indispensable daily necessities in human life. Most electronic products are generally provided with different function keys, and different effects can be achieved by controlling different function keys. At present, a function is generally realized by only one function key. Take a mobile phone as an example, if you want to turn on the phone, you can only use the power button, if you want to turn up the volume, you can only use the volume up button, and if you want to turn down the volume, you can only use the volume down button. Therefore once when one of the function keys is broken, the corresponding function of the function key cannot be realized. If it is not repaired in time, it will affect the use, and even ...
