C-MOS COMPARATOR WITH C-MOS OUTPUT
■ GENERAL DESCRIPTION ■ PACKAGE OUTLINE
The NJU7102A and 04A dual and quad C-MOS
Comparators performing wide operating voltage from 3 to
14V,low operating current and low offset voltage.
The NJU7102A and 04A operated on a single-power-supply
can interface with most of TTL and C-MOS type standard logic
ICs.
■ FEATURES
