Hot-selling and scarce MAX978EEE Single-Supply High-Speed Low-Power Comparators QSOP16 spot stock

Product Descriptions

The MAX976/MAX978/MAX998 dual/quad/single, highspeed,  low-power comparators are optimized for+3V/+5V single-supply applications. They achieve a20ns propagation delay while consuming only 225µA supply current per comparator. The MAX998 features a low-power shutdown mode that places the output in a high-impedance state and reduces supply current to1nA.

The MAX976/MAX978/MAX998 inputs have a commonmode voltage range that extends 200mV below ground. Their outputs are capable of Rail-to-Rail operation without external pull-up circuitry, making these devices ideal for interface with CMOS/TTL logic. All inputs and outputs can tolerate a continuous short-circuit fault condition to either rail. The comparators’ internal hysteresis ensures clean output switching, even with slow-moving input signals.

For space-critical applications, the single MAX998 is available in a 6-pin SOT23 package, the dual MAX976 is available in an 8-pin µMAX package, and the quad MAX978 is available in a 16-pin QSOP package.
