zFeatures
In addition to the features of regular digital transistors.
1) Low saturation voltage, typically
VCE (sat) =40mV at IC / IB=50mA / 2.5mA, makes these
transistors ideal for muting circuits.
2) These transistors can be used at high current levels,
IC=600mA.
3) Two DTC614T chips in a SMT package.
