DTC144EM Datasheet - Rohm

Features

* 1) Built-In Biasing Resistors, R1 = R2 = 47kΩ 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
