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 NPN Types: DTC123JCA

APPLICATION
