Product Summary

The MAX944CSD is a quad high-speed comparator optimized for systems pow-ered from a 3V or 5V supply. The MAX944CSD combines high speed, low power, and rail-to-rail inputs. Propagation delay is 80ns, while supply current is only 350μA per comparator. The input common-mode range of the MAX944CSD extends beyond both power-supply rails. The outputs pull to within 0.4V of either supply rail without external pull-up circuitry, making the MAX944CSD ideal for interface with both CMOS and TTL logic. All input and output pins can tolerate a continuous short-circuit fault condition to either rail.
