... SO (derate 5.88mW/°C above +70°C)................471mW Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability ...

... Rail-to-rail input voltage range and low-volt- age single-supply operation make these devices ideal for portable equipment. The MAX941/MAX942/ MAX944 interface directly to CMOS and TTL logic. Most high-speed comparators oscillate in the linear region because of noise or undesired parasitic feed- back. This tends to occur when the voltage on one input equal to the voltage on the other input ...

... __________Applications Information The high gain bandwidth of the MAX941/MAX942/ MAX944 requires design precautions to realize the comparators’ full high-speed capability. The recom- mended precautions are: , the source Use a printed circuit board with a good, unbro- ken, low-inductance ground plane. 2) Place a decoupling capacitor (a 0.1µF ceramic capacitor is a good choice) as close possible ...
