Product Description

Product Overview

The DTC143XCA is an NPN digital transistor featuring built-in bias resistors (R1 = 4.7k, R2 = 10k) for simplified circuit design. This device enables the configuration of inverter circuits without external input resistors, requiring only the setting of on/off conditions for operation. It is suitable for applications such as inverters, interfaces, and drivers. A complementary PNP type, DTA143XCA, is also available.
