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