1) Built-In Biasing Resistors, R1 = 22ku03a9, R2 = 47ku03a9
2) Built-in bias resistors enable the configuration of
an inverter circuit without connecting external
input resistors (see inner circuit) .
3) Only the on/off conditions need to be set
for operation, making the circuit design easy.
4) Complementary PNP Types: DTA124X series
