Description

The MAX9472EUD is an electronic component model belonging to the IC Chips category. It is a high-speed comparator optimized for systems powered from a 3V or 5V supply. This device combines high speed, low power consumption, and rail-to-rail inputs. It has a propagation delay of 80ns and a supply current of only 350µA per comparator. The input common-mode range extends beyond both power-supply rails, and the outputs can pull to within 0.4V of either supply rail without external pullup circuitry. This makes the MAX9472EUD 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.
