CA3045

Manufacturer Part Number
CA3045
Description
General Purpose NPN Transistor Arrays FN341.4
Manufacturer
Intersil Corporation
Datasheet
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.

... NOTES: 1. The collector of each transistor of the CA3045 and CA3046 is isolated from the substrate by an integral diode. The substrate (Terminal 13) must be connected to the most negative point in the external circuit to maintain isolation between transistors and to provide for normal transistor ac- tion ...
