This document introduces the features and characteristics of CMP401/CMP402 low voltage comparators, including 23 ns or 65 ns propagation delay, single-supply operation, compatibility with 3 V and 5 V logic, separate input and output sections, low power and wide input range.
The CMP401 and CMP402 are quad comparators designed for single-supply operation, compatible with 3 V and 5 V logic. They feature separate input and output sections, allowing the input stage to operate from +3 V to +6 V while the output is supplied by 3 V or 5 V logic. These devices are specified over an extended industrial temperature range of -40°C to +125°C and are available in narrow SO-16 and 16-lead TSSOP packages.
The document provides comprehensive electrical specifications, including offset voltage, input bias current, and propagation delay under various conditions. It also includes absolute maximum ratings, ordering information for different package suffixes (S for SOIC, RU for TSSOP), and typical performance characteristics graphs illustrating propagation delay versus overdrive, temperature, source resistance, and capacitive load.
