... High Speed Design Techniques A substantial amount of design effort has made the LT1713/LT1714 relatively easy to use. As with most high speed comparators, careful attention to PC board layout and design is important in order to prevent oscillations. The most common problem involves power supply by- passing which is necessary to maintain low supply im- pedance ...

... Figure 2. Various Configurations for Introducing Hysteresis LT1713/LT1714 are completely flexible regarding the ap- plication of hysteresis, due to rail-to-rail inputs and the complementary outputs. Specifically, feedback resistors can be connected from one or both outputs to their corresponding inputs without regard to common mode considerations. Figure 2 shows several configurations. ...
