outputs, the UDN2987A and UDN2987LW drivers are used as an

interface between standard low-level logic and relays, motors, sole-

noids, LEDs, and incandescent lamps. The device includes thermal

shutdown and output transient protection/clamp diodes for use with

sustaining voltages to 35 V.

disabled if the thermal shutdown is activated. A common FAULT

output is used to indicate either chip thermal shutdown or any over-

current condition. All outputs are enabled by pulling the common OE/

R input high. When OE/R is low, all outputs are inhibited and the eight

latches are reset.

... SOURCE DRIVER As with all power integrated circuits, the UDN2987A and UDN2987LW have a maximum allowable output current rating. The 500 mA rating does not imply that operation at that value is permitted or even obtainable. The channel output current trip point is specified as -370 mA, minimum; therefore, attempted operation at current levels greater than -370 mA may cause a fault indication and channel shutdown ...
