NTE912
Integrated Circuit
General Purpose Transistor Array
(Three Isolated Transistors and One Differentially–Connected Transistor Pair)
Description:
The NTE912 consists of five general–purpose silicon NPN transistors on a common monolithic sub-
strate in a 14–Lead DIP type package. Two of the transistors are internally connected to form a differ-
entially–connected pair.
The transistors of the NTE912 are well suited to a wide variety of applications in low power systems
in the DC through VHF range. They may be used as discrete transistors in conventional circuits. How-
ever, in addition, they provide the very significant inherent integrated circuit advantages of close elec-
trical and thermal matching.

Note 1. The collector of each transistor is isolated from the substrate by an integral diode. The sub-
strate (Pin13) must be connected to the most negative point in the external circuit to maintain
isolation between transistors and to provide for normal transistor action.
