number of outputs conducting, and duty cycle
are shown on the following pages.
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 tabsDataShee

2. Input current may be limited by maximum
allowable input voltage.
Always order by complete part number, e.g., ULN2068B .
