ROHM Manuals

This document describes the features and characteristics of the DTC114T series NPN digital transistors produced by ROHM. The transistors in this series have built-in bias resistors, which enable the configuration of an inverter circuit without connecting external input resistors. The bias resistors are made of thin-film resistors with complete isolation, allowing for negative biasing of the input and eliminating parasitic effects. Only the on/off conditions need to be set for operation, making circuit design easy. The document also introduces the complementary PNP types and complex types of this series of transistors.

This datasheet provides detailed information on the DTC014T series NPN 100mA 50V digital transistors. These transistors have built-in bias resistors that enable the configuration of an inverter circuit without connecting external input resistors (see inner circuit). The built-in bias resistors consist of thin-film resistors with complete isolation to allow negative biasing of the input. They also have the advantage of completely eliminating parasitic effects. Only the on/off conditions need to be set for operation, making the circuit design easy.

The DTC044T series is an NPN digital transistor with built-in bias resistors, suitable for applications such as switching circuits, inverter circuits, interface circuits, and driver circuits. It features built-in bias resistors that allow the configuration of an inverter circuit without connecting external input resistors. The bias resistors consist of thin-film resistors with complete isolation to enable negative biasing. They also eliminate parasitic effects completely. Only the on/off conditions need to be set for operation, making the circuit design easy.
