ROHM DTD123

Transistors
Digital transistors (built-in resistor)
DTD123TK / DTD123TS
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 thinfilm 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.
