1.5 A DARLINGTON SWITCHES
High-voltage, high-current Darlington arrays ULN2064B/LB
through ULN2069B/LB 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
incandescent 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, ULN2065LB,
ULN2068B, ULN2068LB, ULN2069B, and ULN2069LB are intended
for use with TTL, low-speed TTL, and 5 V MOS logic. The ULN2065B/
LB and ULN2069B/LB are selected for the 80 V minimum output
breakdown specification. The ULN2068B/LB and ULN2069B/LB have
pre-driver stages and are recommended 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’).
