CA3045, CA3046
September 1998 File Number 341.4
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 wellsuitedto
a wide variety ofapplicationsinlowpower systems in the DC
through VHF range. They may be used as discrete
transistors in conventionalcircuits. However,inaddition, they
provide the very significant inherent integrated circuit
advantages of close electrical and thermal matching.

CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operationofthe
device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
NOTES:
1. The collector of each transistor of the CA3045 and CA3046 is isolated from the substrate by an integral diode. The substrate (Terminal13) must
be connected to the most negative point in the external circuit to maintain isolation between transistors and to provide for normal transistor action.
2. θJA is measured with the component mounted on an evaluation PC board in free air.
