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 :DTC143Z series 6) L.
