Features 1) Built-In Biasing Resistors, R1 = R2 = 2.2k.
2) Built-in bias resistors enable the configuration of

an inverter circuit without connecting external input resistors (see equivalent circuit).
DTA123EUA SOT-323 (SC-70)
3) The bias resistors consist of thin-film resistors with complete isolation to allow negative biasing
Inner circuit
of the input. They also have the advantage of completely eliminating parasitic effects.

4) Only the on/off conditions need to be set for
R2
operation, making the circuit design easy.
