DTA124ES3
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 DTC124ES3
