DESCRIPTION
Designed to interfacelogic to a wide variety of high
current,highvoltageloads,thesedeviceseachcon-
tain four NPN darlington switches delivering up to
1.5 A with a specified minimum breakdownof 80 V
and a sustainingvoltage of 50 V. The ULN2065B,
ULN2067B,ULN2069BandULN2071B containin-
tegral suppression diodes for inductive loads and
have common emitters ; the ULN2075B and
ULN2077Bfeature 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,
ULN2071Band ULN2077Bare compatible with 6-
15 VCMOS and PMOS. The ULN2069B and
ULN2071Binclude a predriver stageto provideex-
tragain,reducing the loadon 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 Rth j-amb can be reduced bysoldering the GND
pins to a suitable copperarea of the printedcircuit
board(Fig. 12) orto anexternal heatsink(Fig. 13).
The diagram of figure 14 showsthe maximum dis-
sipablepowerPtot and the Rth j-amb asa functionof
the side ”∝” oftwo equalsquare copperareashav-
ing a thicknessof 35 µ(1.4 mils).
During soldering thepins temperaturemust not ex-
ceed 260 °C and the soldering time must not be
longerthan 12seconds.
The externalheatsinkor printed circuit copperarea
must be connectedto electrical ground.
