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, particularly for inverter circuits, by eliminating the need for external input resistors. Designed for ease of use, these transistors only require setting the on/off conditions for operation, streamlining circuit design. They are suitable for inverter, interface, and driver applications. Complementary NPN types are available in the DTC144E series.
