Features:
・ Built-In Biasing Resistors, R1 = 4.7kΩ, R2 = 10kΩ・ Built-in bias resistors enable the configuration of an inverter circuit without connecting external input resistors (see inner circuit) .
・ 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.
・ Only the on/off conditions need to be set for operation, making the circuit design easy.
・ Complementary PNP Types: DTA043X series
・ Lead Free/RoHS Compliant.
