DTD113EK
Features
1) Built-in bias resistors enable the configuration of an inverter
circuit without connecting external input resistors (see
equivalent circuit).
2) 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.
3) Only the on / off conditions need to be set for operation,

making the device design easy.
