Features
1) Built-In Biasing Resistors, R1 = R2 = 47kΩ
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: DTA144E series
6) Complex transistors: EMH2/ UMH2N/ IMH2A/ EMH6/ UMH6N/ IMH6A （NPN type）
7) Lead Free/RoHS Compliant.

Application
    Switching circuit, Inverter circuit, Interface circuit, Driver circuit
