Datasheet Maxim MAX909CSA — 数据表

Not Recommended for New Designs
The MAX909 was manufactured for Maxim by an outside wafer
foundry using a process that is no longer available. It is not
recommended for new designs. A Maxim replacement or an industry
second-source may be available. The data sheet remains available for
existing users. The other parts on the following data sheet are not
affected.
For further information, please see the QuickView data sheet for this
part or contact technical support for assistance. 19-0129; Rev 7; 1/06 Dual/Quad/Single, High-Speed, Ultra-Low-Power,
Single-Supply TTL Comparators
The MAX907/MAX908/MAX909 are dual/quad/single,
high-speed, ultra-low-power voltage comparators
designed for use in systems powered from a single
+5V supply; the MAX909 also accepts dual ±5V supplies. Their 40ns propagation delay (with 5mV input
overdrive) is achieved with a power consumption of
only 3.5mW per comparator. The wide input commonmode range extends from 200mV below ground (below
the negative supply rail for the MAX909) to within 1.5V
of the positive supply rail.
Because they are micropower, high-speed comparators that operate from a single +5V supply and include
built-in hysteresis, these devices replace a variety of
older comparators in a wide range of applications.
MAX907/MAX908/MAX909 outputs are TTL-compatible,
requiring no external pullup circuitry. All inputs and outputs can be continuously shorted to either supply rail …
