This comparator is of the OPEN-COLLECTOR output type.You can find 8 terminals of the comparator.Supplied by 5V voltage, the comparator can accomplish the many demanding tasks.The comparator essentially has a COMPARATOR amplifier that has very high gain.Users should not apply the part to where the ambient temperature is higher than 125°C .In places colder than -55°C , this part can't assure precise measurement and detection.
