R
100mA / 50V Digital transistors
(with built-in resistors)
DTC123EM / DTC123EE / DTC123EUA / DTC123EKA
zApplications
Inverter, Interface, Driver
zFeatures
1) Built-in bias resistors enable the configuration of an inverter circuit without connecting external input resistors (see the
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.
