lFeatures
1) Built-In Biasing Resistors, R1 = R2 = 4.7kΩ
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 NPN Types: DTC143EKA FRA
