LM3146 High Voltage Transistor Array
General Description
The LM3146 consists of five high voltage 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
provide the very significant inherent integrated circuit ad-
vantages of close electrical and thermal matching The
LM3146 is supplied in a 14-lead molded dual-in-line pack-
age for applications requiring only a limited temperature
range
