General Purpose High Current NPN
Transistor Arrays
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.
Features
• CA3081 - Common Emitter Array
• CA3082 - Common Collector Array
• Directly Drive Seven Segment Incandescent Displays and
Light Emitting Diode (LED) Display
• 7 Transistors Permit a Wide Range of Applications in
Either a Common Emitter (CA3081) or Common Collector
(CA3082) Configuration
