... Not Recommended for New Designs The MAX909 was manufactured for Maxim by an outside wafer foundry using a process that is no longer available not recommended for new designs. A Maxim replacement or an industry second-source may be available. The data sheet remains available for existing users. ...

... A separate supply pin for extending the analog input range down to -5V is also provided. The dual MAX907 and single MAX909 are available in 8-pin DIP and SO packages, and the quad MAX908 is available in 14-pin DIP and SO packages. These com- parators are ideal for single +5V-supply applications that require the combination of high speed, precision, and ultra-low power dissipation ...

... DC parameters are within the specified limits. V For the MAX909, propagation delay is typical only and there is no guaranteed maximum limit. Note 10: Differential Propagation Delay is specified as the difference between any two channels in the MAX907/MAX908 (both out- puts making either a low-to-high or a high-to-low transition). ...

... Noise or undesired parasitic AC feedback cause most high-speed comparators to oscillate in the linear region (i.e., when the voltage on one input near the voltage on the other input). The MAX907/MAX908/ MAX909 eliminate this problem by incorporating inter- nal hysteresis. When the two comparator input voltages are equal, hysteresis effectively causes one comparator input voltage to move quickly past the other, thus taking the input out of the region where oscillation occurs ...

... Solder the device directly to the printed circuit board instead of using a socket. Overdriving the Inputs The inputs to the MAX907/MAX908/MAX909 may be driven beyond the voltage limits given in the Absolute Maximum Ratings, as long as the current flowing into the device is limited to 25mA. However, if the inputs are overdriven, the output may be inverted ...
