MAX944MJD Datasheet PDF - Maxim Integrated

●General Description

●The MAX941/MAX942/MAX944 are single/dual/quad high-speed comparators optimized for systems powered from a 3V or 5V supply. These devices combine 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 MAX941/MAX942/MAX944 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.
