Features
1) Built-In Biasing Resistor
2) Built-in bias resistors enable the configuration of
    an inverter circuit without connecting external
    input resistors (see inner circuit) .
3) The bias resistors consist of thin-film resistors
    with complete isolation to allow negative biasing
    of the input. They also have the advantage of
    completely eliminating parasitic effects.
4) Only the on/off conditions need to be set
    for operation, making the circuit design easy.
5) Complementary NPN Types: DTC125T series
6) Lead Free/RoHS Compliant.

APPLICATION
   Switching circuit, Inverter circuit, Interface circuit,
   Driver circuit
