TIGER ELECTRONIC CO.,LTD
Digital transistors (built-in resistors)
DTC143TM/DTC143TE/DTC143TUA
DTC143TKA /DTC143TSA/ DTC143TCA
DIGITAL TRANSISTOR (NPN)
Equivalent Circuit
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
