LB1287

Ordering number:ENN266E Monolithic Digital IC LB1287, 1288 Darlington Transistor Array 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.
