MAX997/MAX999 Single/Dual/Quad, Ultra-High-Speed, +3V/+5V,
Beyond-the-Rails Comparators General Description 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-theRails^TM, and the outputs can sink or source 4mA to within
0.52V of GND and VCC. 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 5-pin SOT23
package. The single MAX961/MAX997 and dual MAX962
are available in space-saving 8-pin μMAX® packages. Applications
