Maxim MAX9987ETP+

Overview

The MAX976/MAX978/MAX9987ETP dual/quad/single, high-speed, low-power comparators are optimized for +3V/+5V single-supply applications. They achieve a 20ns propagation delay while consuming only 225μA supply current per comparator. The MAX9987ETP features a low-power shutdown mode that places the output in a high-impedance state and reduces supply current to 1nA. The MAX976/MAX978/MAX9987ETP inputs have a common-mode voltage range that extends 200mV below ground. Their outputs are capable of rail-to-rail operation without external pullup 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 MAX9987ETP 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.
