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 80 V
and a sustaining voltage of 50 V. The ULN2065B,
ULN2067B, ULN2069B and ULN2071B contain in-
tegral suppression diodes for inductive loads and
have common emitters ; the ULN2075B and
ULN2077B feature isolated darlington pinouts and
are intended for applications such as emitter fol-
lower configurations. Inputs of the ULN2065B,
ULN2069B and ULN2075B are compatible with
popular 5 V logic families and the ULN2067B,
ULN2071B and ULN2077B are compatible with 6-
15 VCMOS and PMOS. The ULN2069B and
ULN2071B include a predriver stage to provide ex-
tragain, reducing the load on control logic.

Notes : 1. Input voltage is with reference to the substrate (no connection to any other pins) for the ULN2075B and ULN2077B
reference is ground for all other types.
2. Input current may be limited by maximum allowable input voltage.

MOUNTING INSTRUCTIONS
The R
th 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).
The diagram of figure 14 shows the maximum dis-
sipable power P
tot
and the R
th j-amb
as a function of
the side "
" of two equal square copper areas hav-
ing a thickness of 35
(1.4 mils).
During soldering the pins temperature must not ex-
ceed 260
C and the soldering time must not be
longer than 12 seconds.
The external heatsink or printed circuit copper area
must be connected to electrical ground.

Used as Heatsink.
