MAX942ESA+

MAX942ESA+ is a dual, high-speed comparator optimized for systems powered from a 3V or 5V supply. This device combines high-speed, low-power, and rail-to-rail inputs. The input common-mode range of this device extends beyond both power-supply rails. The outputs pull to within 0.4V of either supply rail without external pull-up circuitry, making these devices 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. Internal hysteresis ensures clean output switching, even with slow-moving input signals. Applications include 3V/5V systems, battery-powered systems, threshold detectors/discriminators, line receivers, zero-crossing detectors, and sampling circuits.
