Overview
These ICs have circuit configuration of 5-unit Darlington transistor array consisting of NPN transistors and are capable of causing small input current to provide large current drive. They can be advantageously incorporated in equipment because the specially designed 14-pin DIP makes such equipment more compact.

Features
• Large maximum drive current : 400mA
• Large allowable power dissipation : 1.15W
• Wide range of operating supply voltage. LB1287 5 to 30V, LB1288 5 to 20V
• Wide range of operating temperature. –20 to +80˚C
• Large current-amplification factor : 2000 or more

Applications
• Various types of driver (relay, solenoid, motor, etc.).
• Display segment or digit driver (LED, lamp).
• Interface to MOS or bipolar logic IC.
• Power amplification of pulse (fan-out extension, etc.).
