The MAX978ESE+ is a single supply, high speed, low power quad comparator in 16 pin NSOIC package. This comparator is optimized for +3V/+5V single supply applications, it achieve a 20ns propagation delay while consuming only 225μA supply current per comparator. Device inputs have a common mode voltage range that extends 200mV below ground and outputs are capable of rail to rail operation without external pull-up circuitry, making device ideal for interface with CMOS/TTL logic. All inputs and outputs can tolerate a continuous short circuit fault condition to either rail. The comparator's internal hysteresis ensures clean output switching even with slow moving input signals.
