Features

TUMT6orParameter

1) Built-In Biasing Resistors
2) Two DTC643T chips in one package.
3) Low saturation voltage, typicallyVCE(sat) =40mV at IC / IB=50mA / 2.5mA, makes thesetransistors ideal for muting circuits.
4) These transistors can be used at high current levels,
IC=600mA.
Inner circuit5) Built-in bias resistors enable the configuration of
US6H23an inverter circuit without connecting external
BaseCollector(5)(6)
input resistors (see equivalent circuit).
6) The bias resistors consist of thin-film resistors
R1
with complete isolation to allow negative biasingof the input. They also have the advantage of
R1
completely eliminating parasitic effects.
(1)(2)7) Lead Free/RoHS Compliant.
