NTE929
Integrated Circuit
General Purpose, High Current, NPN Transistor Array
Description:
The NTE929 is a versatile array of five high–current (to 100mA) NPN transistors on a common mono-
lithic substrate. In addition, two of these transistors (Q1 and Q2) are matched at low currents (i.e.
1mA) for applications in which offset parameters are of special importance.
Independent connections for each transistors plus a separate terminal for the substrate permit maxi-
mum flexibility in circuit design.
Features:
D High IC 100mA max
D Low VCEsat (at 50mA) 0.7V max.
D Matched pair (Q1 and Q2)
V10 (VBE matched): ±5mV max.
I10 (at 1mA): 2.5µA max.
D 5 independent transistors plus separate substrate connection.
Applications:
D Signal processing and switching systems operating from DC to VHF
D Lamp and relay driver
D Differential amplifier
D Temperature–compensated amplifier
D Thyristor firing
Absolute Maximum Ratings: (TA = +25°C unless otherwise specified)

Note 1. The collector of each transistor of the NTE929 is isolated from the substrate by an integral
diode. The substrate must be connected to a voltage which is more negative than any collec-
tor voltage in order to maintain isolation between transistors and provide normal transistor
action. To avoid undesired coupling between transistors, the substrate terminal (Pin5)
should be maintained at either DC or signal (AC) ground. A suitable bypass capacitor can
be used to establish a signal ground.
