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