DTA124EN3
Spec. No. : C263N3
Issued Date : 2003.12.26
Revised Date : 2004.01.15
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 positive 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 DTC124EN3
