  • Low resistance input protection circuit
    Patent number: 6137338
    Abstract: An input circuit is designed with an external terminal (104). A first input transistor (108) has a control gate coupled to the external terminal by a low resistance path (104). The first input transistor has a current path coupled to an output terminal (120). A first series transistor (110) has a control gate and a current path. The current path of the first series transistor is connected in series with the current path of the first input transistor. A primary clamp (102) is coupled to the external terminal.
