NTE NTE2079

NTE2079
Integrated Circuit
7–Stage Darlington Transistor Array
Description:
The NTE2079 is a 7–channel sink driver in a 16–Lead DIP type package and consists of 14 NPN
transistors connected to form seven high current gain driver pairs.
Features:
D High Output Sustaining Voltage to 40V
D High Output Sink Current to 400mA
D PMOS Compatible Input
D Wide Operating Temperature Range (TA = –20° to +75°C)
Application:
Relay and printer driver, LED or Incandescent display digit driver, Interfacing for standard MOS/BI POLAR
logics.
Function:
The NTE2079 is comprised of seven NPN Darlington drivers pairs with 20kΩ series input resistors.
All emitters and the substrate are connected together to Pin8. The outputs are capable of sinking
400mA and will withstand 40V in the OFF state.
