The MAX9140/MAX9141/MAX9142/MAX9144 are high-speed comparators optimized for systems powered from a 3V or 5V supply.
The MAX9140, MAX9141, MAX9142, and MAX9144 are high‑speed, low‑power comparators optimized for 3 V or 5 V single‑supply operation. They feature rail‑to‑rail input ranges, internal hysteresis, and CMOS/TTL‑compatible outputs, making them suitable for portable equipment, line receivers, and threshold detectors.
The datasheet includes absolute maximum ratings, detailed electrical characteristics, typical operating curves, pin descriptions, and package information. Design recommendations such as proper PCB grounding and decoupling are also provided to ensure full performance of these comparators.
