NTE910 & NTE910D Integrated Circuits HighSpeed Differential Comparator Description: The NTE910 (8Lead Metal Can) and NTE910D (14Lead DIP) are differential voltage comparators intended for applications requiring high accuracy and faast response times. The device is useful as a variable threshold Schmitt trigger, a pulseheight discriminator, a voltage comparator in highspeed A/D converters, a memory sense amplifier or a high noise immunity line receiver. The output of the comparator is compatible with all intergrated logic forms.
