Open-drain outputs can be useful for analog weighting, summing, and limiting as well as digital logic. An open drain terminal is connected to ground when a high voltage (logic 1) is applied to the gate, yet presents a high impedance when a low voltage (logic 0) is applied to the gate.
The End The Gulf of Tonkin Incident August 2nd- The USS Maddox engages three North Vietnamese Torpedo Boats August 4th- USS Maddox and Turner Joy report further engagement in the Tonkin Gulf Gulf of Tonkin Resolution August 7th Congress passes a joint resolution that allows President Johnson to use authority to support the states of Southern Vietnam. This is not a declaration of war.
Yet 40 years after the incident, evidence now available reveals that the Johnson administration may have misled the public and Congress about the nature of the Tonkin incident. The details of the debate around the Tonkin Gulf Resolution reveal that some of the senators accepted Cold War theories of the domino effect and containment, which may have limited their ability to consider a range of responses to the incident.
