Product Description
Product Overview
The DTA144E series is a range of PNP digital transistors featuring built-in bias resistors (R1 = R2 = 47k). This integrated design simplifies circuit configuration, enabling the creation of inverter circuits without external input resistors. Designed for ease of use, these transistors only require setting of on/off conditions for operation, making circuit design straightforward. They are suitable for applications such as inverters, interfaces, and drivers. Complementary NPN types are available in the DTC144E series.
