LM3046

Transistor Array

General Description

The LM3046 consists of five general purpose silicon NPN

transistors on a common monolithic substrate. Two of the

transistors

are

internally

connected

to

form

a

differentially-connected pair. The transistors are well suited

to a wide variety of applications in low power system in the

DC through VHF range. They may be used as discrete tran-

sistors in conventional circuits however, in addition, they pro-

vide the very significant inherent integrated circuit advan-

tages of close electrical and thermal matching. The LM3046

is supplied in a 14-lead molded dual-in-line package.
