4.75 to 35 V driver supply voltage
Output enable-disable (OE/R)
350 mA output source current
Overcurrent protected
Internal ground clamp diodes
Output Breakdown Voltage 35 V minimum
TTL, DTL, PMOS, or CMOS compatible inputs
Internal Thermal Shutdown (TSD)
Providing overcurrent protection for each of its eight
sourcing outputs, the UDN2987LW-6 driver is used as an
interface between standard low-level logic and relays, motors,
solenoids, LEDs, and incandescent lamps. This device includes
thermal shutdown and output transient protection/clamp diodes
for use with sustaining voltages to 35 V.
In this driver, each channel includes a latch to turn off that
channel if the maximum channel current is exceeded. All
channels are disabled if the thermal shutdown is activated. A

common FAULT output is used to indicate either chip thermal
shutdown or any overcurrent 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. The
OE/R function can be especially important during power-up,
in preventing floating inputs from turning on the outputs.
Under normal operating conditions, each of eight outputs
will source in excess of 100 mA continuously at an ambient
temperature of 25°C and a supply of 35 V. The overcurrent
fault circuit will protect the device from short-circuits to ground
with supply voltages of up to 30 V.
