Digital transistors (built-in resistors)
DTA143TE/DTA143TUA/DTA143TKA
/DTA143TSA/ DTA143TCA
DIGITAL TRANSISTOR (PNP)
FEATURES
1. Built-in bias resistors enable the configuration of an inverter circuit without connecting external input
resistors(see equivalent circuit).
2. The bias resistors consist of thin-film resistors with complete isolation to allow negative biasing of the
input.They also have the advantage of almost completely eliminating parasitic effects.
3. Only the on/off conditions need to be set for operation, making device design easy.
