l Features
1) Built-In Biasing Resistors.
2) Built-in bias resistors enable the configuration of GND
an inverter circuit without connecting external
DTA043ZUB input resistors (see inner circuit). (SC-85)
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 l Inner circuit
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 :DTC043Z series 6) Lead Free/Ro HS Compliant.
