MAX997集成电路（IC）的专用逻辑器件规格书PDF中文资料

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.
