LM261
LM261 is High Speed Differential Comparators manufactured by National Semiconductor.
Description
The LM161 LM261 LM361 is a very high speed differential input plementary TTL output voltage parator with improved characteristics over the SE529 NE529 for which it is a pin-for-pin replacement The device has been optimized for greater speed performance and lower input offset voltage Typically delay varies only 3 ns for over-drive variations of 5 m V to 500 m V It may be operated from op amp supplies (g15V) plementary outputs having maximum skew are provided Applications involve high speed analog to digital converters and zero-crossing detectors in disk file systems
