The datasheet introduces the features of CMP401/CMP402.
The CMP401 and CMP402 are quad comparators offered in 23 ns (CMP401) and 65 ns (CMP402) propagation‑delay versions. They operate from a single supply of +3 V to +6 V, with separate analog and digital supplies, and feature low power consumption and a wide input voltage range of –5 V to +3.9 V.
The devices are specified over an industrial temperature range (‑40 °C to +125 °C) and are available in 16‑pin DIP, narrow SO‑16, and 16‑lead TSSOP packages. Detailed electrical specifications, absolute maximum ratings, and typical performance curves are provided in the data sheets.
