1. Allowable combinations of output current,
number of outputs conducting, and duty cycle
are shown on the following pages.
2. Input current may be limited by maximum
allowable input voltage.
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 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/LB, ULN2065B/LB, ULN2068B/LB,
and ULN2069B/LB 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’).
