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.
The MAX961‑MAX964/MAX997/MAX999 family are low‑power, ultra‑high‑speed comparators with internal hysteresis, optimized for single‑supply operation at +3 V or +5 V. They feature a Beyond‑the‑Rails input range, 4 mA source/sink capability, and optional latch‑enable functionality.

| Propagation delay | 4.5 ns |
|---|---|
| Supply current per comparator | 5 mA |
| Output sink/source current | 4 mA |
| Input common‑mode range | 100 mV beyond the rails |
The typical propagation delay is 4.5 ns with a 5 mV overdrive.
Each comparator draws about 5 mA of supply current.
The input common‑mode range extends 100 mV beyond both supply rails.
