Maxim Integrated

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 sup-

ply 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 fea-

ture. Latch enable allows the user to hold a valid com-

parator 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.
