NTE910 & NTE910D
Integrated Circuits
High−Speed Differential Comparator
Description:
The NTE910 (8−Lead Metal Can) and NTE910D (14−Lead 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 pulse−height discriminator, a voltage comparator in high−speed
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.
