Features
1) Built-In Biasing Resistors,
    R1 = 2.2kΩ, R2 = 4.7kΩ
2) Built-in bias resistors enable the configuration of
    an inverter circuit without connecting external
    input resistors (see inner circuit) .
3) Only the on/off conditions need to be set
    for operation, making the circuit design easy.
4) Complementary PNP Types: DTB123YK FRA

APPLICATION
   INVERTER, INTERFACE, DRIVER
