Six-way each reset type touch switch circuit

Published:2011/4/27 20:43:00 Author:Nicole | Keyword: touch switch | From:SeekIC

This switch circuit is a touch switch circuit, if one of inputs is 0 , then the corresponding output is 0 , the others are 1 . This circuit has two groups, the selection control can achieve two ways by 6/3 terminal. When 6/3= 1 , it will become six-way each reset type action; when 6/3= 0 , it will become two groups three-way each reset type action. The output is open drain(N ditch)type, when VDD=12V, the input current of all kinds output terminal can reach 30mA. Input terminal 100kΩ current takes the action of limiting current, but it is no need to connect capacitance to prevent wobble and other error trigger.
