Product Description

Product Overview

The DTC114T series NPN digital transistor features built-in biasing resistors, simplifying circuit design by eliminating the need for external input resistors. This allows for easy configuration of inverter circuits, requiring only the setting of on/off conditions. Complementary PNP types are available in the DTA114T series. These transistors are ideal for applications such as inverters, interfaces, and drivers.
