llFeatures
　　 　　
1) Built-In Biasing Resistors,
　 R
1
= 2.2kΩ, R
2
= 10kΩ
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: DTA123Y series
