REI Datasheet
CA3081, CA3082
General Purpose High Current NPN Transistor Arrays
The CA3081 and CA3082 consist of seven high current (to 100mA) silicon NPN transistors on a
common monolithic substrate. The CA3081 is connected in a common emitter configuration and the
CA3082 is connected in a common collector configuration.
The CA3081 and CA3082 are capable of directly driving seven segment displays, and light emitting
diode (LED) displays. These types are also well suited for a variety of other drive applications,
including relay control and thyristor firing.
