Datasheet DTC144EB, DTC144EE, DTC144EKA, DTC144EM, DTC144EUA Datasheet (ROHM) [ru]

100mA / 50V Digital transistors
(with built-in resistors)

DTC144EB / DTC144EM / DTC144EE / DTC144EUA / DTC144EKA

zApplications
Inverter, Interface, Driver

zFeatures

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 the device design easy.
