1.5 A DARLINGTON SWITCHES
High-voltage, high-current Darlington arrays ULN2064B/LB
through ULN2069B are designed for interface between low-level logic
and a variety of peripheral loads such as relays, solenoids, dc and
stepper motors, magnetic print hammers, multiplexed LED and incan-
descent displays, heaters, and similar loads. Output OFF voltage
ratings of 50 V and 80 V are available. These quad drivers can drive
resistive loads to 480 watts (1.5 A x 80 V, 26% duty cycle). For
inductive loads, sustaining voltages of 35 V and 50 V at 100 mA are
specified.
Quad drivers ULN2064B, ULN2064LB, ULN2065B, ULN2068B,
ULN2068LB, and ULN2069B are intended for use with TTL, low-speed
TTL, and 5 V MOS logic. The ULN2065B and ULN2069B are selected
for the 80 V minimum output breakdown specification. The
ULN2068B/LB and ULN2069B have pre-driver stages and are recom-
mended for applications requiring high gain (low input-current loading).
Quad-driver arrays are supplied with heat-sink contact tabs in 16-pin
plastic DlPs (suffix ‘B’) and 20-lead surface-mountable wide-body
SOICs (suffix ‘LB’).
