NPN Digital Transistors (Built-in Resistors)
DTD143EN3
Spec. No. : C378N3 Issued Date : 2004.01.15 Revised Date : Page No. : 1/4
Features
• Built-in bias resistors enable the configuration of an inverter circuit without connecting external input resistors (see equivalent circuit).
• The bias resistors consist of thin-film resistors with complete isolation to allow negative biasing of the input. They also have the advantage of almost completely eliminating parasitic effects.
• Only the on/off conditions need to be set for operation, making device design easy. • Complements the DTB143EN3
