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.
