  • Publication number: 20030062944
    Abstract: A high-speed bank select multiplexer latch may be coupled to a pair of differential output nodes and configured to capture and retain an output on the pair of differential output nodes responsive to two or more pairs of differential data inputs being active. A first subcircuit including a first N-channel transistor and a second N-channel transistor is configured to receive at least a first input signal and a second input signal and to drive a first output on a first output node responsive to either of the first input signal or the second input signal being active. Additionally, a second subcircuit including a third N-channel transistor and a fourth N-channel transistor is configured to receive at least a third input signal and a fourth input signal and to drive a second output on a second output node responsive to either of the third input signal or the fourth input signal being active.

  • Patent number: 5994266
    Abstract: The present invention relates to pesticidal compositions comprising an amount of a UV sensitive pesticide and a lignin as a UV sunscreen in an effective amount to protect the pesticide against inactivation by UV radiation for extending the persistence of the UV sensitive pesticide in the natural environment to control a pest and/or for reducing the amount of the pesticide typically needed to be a commercially effective pesticide. The present invention also relates to a method for protecting a UV sensitive pesticide against inactivation by UV radiation. The present invention further relates to a method for controlling a pest comprising exposing the pest to the pesticidal compositions of the present invention.
