DESCRIPTION
Designed to interface logic to a wide variety of high
current, high voltage loads, these devices each con-
tain four NPN darlington switches delivering up to
1.5 A with a specified minimum breakdown of 50 V
and a sustaining voltage of 35 V measured at 100
mA. The ULN2064B, ULN2066B, ULN2068B and
ULN2070B contain integral suppression diodes for
inductive loads have common emitters. The
ULN2074B and ULN2076B feature isolated dar-
lington pinouts and are intended for applications
such as emitter follower configurations. Inputsof the
ULN2064B, ULN2068B and ULN2074B are com-
patible with popular 5 V logic families and the
ULN2066B and ULN2076B are compatible with 6-
15 V CMOS and PMOS. Types ULN2068B and
ULN2070B include a predriver stage to reduce load-
ing on the control logic.

Notes : 1. Input voltage is with reference to the substrate (no connection to any other pins) for the ULN2074B and ULN2076B
reference is ground for all other types.
2. Input current may be limited by maximum allowable input voltage.

MOUNTING INSTRUCTIONS
The Rth j-amb can be reduced by soldering the GND
pins to a suitable copper area of the printed circuit
board (Fig. 12) or to an external heatsink (Fig. 13).
During soldering the pins temperature must not ex-
ceed 260 °C and the soldering time must not be
longer than 12 seconds.
The diagram of Figure 14 shows the maximum dis-
sipable power Ptot and the Rth j-amb as a function of
the side "α" of two equal square copper areas hav-
ing a thickness of 35 µ (1.4 mils).
The external heatsink or printed circuit copper area
must be connected to electrical ground.
