Product Description

Product Overview

The DTC144E series is a digital transistor (bias resistor built-in transistor) designed for inverter, interface, and driver applications. Featuring built-in biasing resistors (R1 = R2 = 47k), these transistors simplify circuit design by eliminating the need for external input resistors, allowing for operation based solely on on/off conditions. The series offers complementary PNP types and is available in various package configurations.
