DTC143ZE/DTC143ZUA/DTC143ZCA
DTC143ZKA/DTC143ZSA
Digital Transistor(NPN)

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.
