Features
1) Built-In Biasing Resistors
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 PNP Types :DTA143Z series
6) Complex transistors :
    EMH25 /EMG8 /UMG8N（NPN type）
7) Lead Free/RoHS Compliant.
   
Application
