/Clamp Diode and Strobe
Description:
The NTE2073 is a 6Channel sink driver consisting of 12 NPN transistors to form high current gain
driver pairs.
Each input has a diode and 20k
resistor in series to allow a negative voltage input. All inputs can
be controlled simultaneously by a strobe input at Pin1.
The power supply of the predrivers is connected to Pin16. All emitters and the substrate are con-
nected together to Pin8. Each output has an integral diode for inductive load transient suppression
and the cathodes of the diodes are connected to Pin9.
The outputs are capable of sinking 320mA and will withstand 20V in the OFF state.
