General Purpose NPN Transistor Array
The CA3046 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 of the CA3046 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. However, in addition, they
provide the very significant inherent integrated circuit
advantages of close electrical and thermal matching.
