CA3045, CA3046

General Purpose NPN Transistor Arrays

The CA3045 and CA3046 each consist 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 CA3045 and 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.
