NJM360 HIGH SPEED DIFFERENTIAL COMPARATOR = GENERAL DESCRIPTION The NJM360 is a very high speed differential input, complementaly TTL output voltage comparator. The device has been optimized for greater speed, input impedance and fan-out and lower input offset volt- age. Applications involve high speed analog to digital convertors and. zero-crossing detectors in disc file systems. m FEATURES @ Operating Voltage (t4.5V~ +6.5V) @ High Speed Guarrantee (20ns max.) @ Both output delay time has been precisely adjusted @ Complimentally TTL Output @ High Input Impedance @ Stablized Speed for Over Driving Change @ Bipolar Technology @ = Fan-out is 4 @ Low Input Offset voltage @ Package Outline DIP8, DMP8, (SSOP8) = PIN CONFIGURATION Oooo WJM3300 NJM360M @ EQUIVALENT CIRCUIT yt PIN FUNCTION 1.
