lFeatures

lInner circuit

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 biasingof the input. They also have the advantage ofcompletely eliminating parasitic effects.
4) Complementary PNP Types :DTB114GK
5) Lead Free/RoHS Compliant.
