The MAX961–MAX964/MAX997/MAX999 are low-power, ultra-high-speed comparators with internal hysteresis. These devices are optimized for single +3V or +5V operation. The input common-mode range extends 100mV Beyond-the-Rails?, and the outputs can sink or source 4mA to within 0.52V of GND and V_CC. Propagation delay is 4.5ns (5mV overdrive), while supply current is 5mA per comparator.

The MAX961/MAX963/MAX964 and MAX997 have a shutdown mode in which they consume only 270μA supply current per comparator. The MAX961/MAX963 provide complementary outputs and a latch-enable feature. Latch enable allows the user to hold a valid comparator output. The MAX999 is available in a tiny SOT23-5 package. The single MAX961/MAX997 and dual MAX962 are available in space-saving 8-pin μMAX? packages.
