50V - 1.5A QUAD DARLINGTON SWITCHES OUTPUT CURRENT TO 1.5 A EACH DAR-
LINGTON. MINIMUM BREAKDOWN 50 V. SUSTAINING VOLTAGE AT LEAST 35 V. INTEGRAL SUPPRESSION DIODES
(ULN2064B, ULN2066B, ULN2068B and
ULN2070B). ISOLATED DARLINGTON PINOUT
(ULN2074B, ULN2076B). VERSIONS COMPATIBLE WITH ALL POPU-
LAR LOGIC FAMILIES
PIN CONNECTIONS AND ORDER CODES
DESCRIPTIONDesigned 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. Inputs of 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.

MOUNTING INSTRUCTIONSThe 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).
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).
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.
