NTE919D
Integrated Circuit
High Speed Dual Comparator
Description:
The NTE919D is a precision high speed dual comparator fabricated on a single monolithic chip. This
devices is designed to operate over a wide range of supply voltages down to a single 5V logic supply
and ground. Further, it has higher gain and lower input currents than devices like the NTE910. The
uncommitted collector of the output stage makes it compatible with RTL, DTL, and TTL as well as
capable of driving lamps and relays at currents up to 25mA.
Although designed primarily for applications requiring operation from digital logic supplies, the
NTE919D is fully specified for power supplies up to
鹵15V.

Note 1. For supply voltages less than
鹵15
the absolute maximum input voltage is equal to the supply
voltage.
Note 2. The maximum junction temperature is 85擄C. For operating at elevated temperatures, de-
vices must be derated based on a thermal resistance of 100擄C/W, junction to ambient.
