lFeatures

lInner circuit

1) Built-In Biasing Resistors.
2) Two DTC143Z chips in one package.
3) Built-in bias resistors enable the configuration of
an inverter circuit without connecting external
input resistors (see inner circuit).
4) 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.
5) Only the on/off conditions need to be set foroperation, making the circuit design easy.
6) Lead Free/RoHS Compliant.
