MAX961–MAX964/
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-the-
Rails™, 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 sup-
ply current per comparator. The MAX961/MAX963 pro-
vide 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

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.
