Digital Transistors (PNP)

The DTA144EM/DTA144EE/DTA144EUA/DTA144EKA/DTA144ECA/DTA144ESA are PNP digital transistors featuring built-in bias resistors. This integration simplifies circuit design by eliminating the need for external input resistors, allowing for direct setting of on/off conditions. The thin-film bias resistors offer complete isolation and minimize parasitic effects, enabling positive input biasing. These transistors are suitable for inverter circuit configurations.
