EMH9 / UMH9N / IMH9A
NPN 100mA 50V Complex Digital Transistors
(Bias Resistor Built-in Transistors)
Outline
Features
1) Built-In Biasing Resistors.
2) Two DTC114Y chips in one package.
3) Built-in bias resistors enable the configuration of
an inverter circuit without connecting external
input resistors (see inner circuit).
4) The bias resistors consist of thin-film resistors
with complete isolation to allow negative biasing Inner circuit
of the input. They also have the advantage of
completely eliminating parasitic effects.
5) Only the on/off conditions need to be set for
operation, making the circuit design easy.
6) Lead Free/RoHS Compliant.
Application
Inverter circuit, Interface circuit, Driver circuit

cation, consumer systems, gaming/entertainment sets) as well as the applications indicated in
this document.
The Products specified in this document are not designed to be radiation tolerant.
For use of our Products in applications requiring a high degree of reliability (as exemplified
below), please contact and consult with a ROHM representative : transportation equipment (i.e.
cars, ships, trains), primary communication equipment, traffic lights, fire/crime prevention, safety
equipment, medical systems, servers, solar cells, and power transmission systems.
Do not use our Products in applications requiring extremely high reliability, such as aerospace
equipment, nuclear power control systems, and submarine repeaters.
ROHM shall have no responsibility for any damages or injury arising from non-compliance with
the recommended usage conditions and specifications contained herein.
