HIGH SPEED DIFFERENTIAL COMPARATOR
■ GENERAL DESCRIPTION ■ PACKAGE OUTLINE
The NJM360 is a very high speed differential input, complementary
TTL output voltage comparator. The device has been optimized for
greater speed, input impedance and fan-out and lower input offset
voltage.
Applications involve high speed analog to digital converters and
zero-crossing detectors in disc file systems.
■ FEATURES
● Operating Voltage ( ±4.5V~±6.5V )
● High Speed Guarantee ( 20ns max. )
● Both output delay time has been precisely adjusted
● Complementary TTL Output
● High Input Impedance
● Stabilized Speed for Over Driving Change
● Bipolar Technology
● Fan-out is 4
● Low Input Offset Voltage
● Package Outline DIP8, DMP8, SOP8 JEDEC 150mil
