UDN2987x-6  
DABIC-5 8-Channel Source Driver  
with Overcurrent Protection  
Package A, 20-pin DIP  
Package LW, 20-pin SOIC-W  
Features  
Providing overcurrent protection for each of its eight  
sourcing outputs, the UDN2987A-6 and UDN2987LW-6  
drivers are used as an interface between standard low-level logic  
and relays, motors, solenoids, LEDs, and incandescent lamps.  
These devices include thermal shut down and output transient  
protection/clamp diodes for use with sustaining  
voltages to 35 V.  
Approximate Scale 1:1  
In these drivers, 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  
ꢀOutput Breakdown Voltage 35 V minimum  
ꢀTTL, DTL, PMOS, or CMOS compatible inputs  
ꢀInternal Thermal Shut Down (TSD)  
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 over-current  
fault circuit will protect the device from short-circuits to ground  
with supply voltages of up to 30 V.  
Applications  
ꢀRelays  
ꢀMotors  
ꢀSolenoids  
ꢀLEDs  
The inputs are compatible with 5 and 12 V logic systems:  
TTL, Schottky TTL, DTL, PMOS, and CMOS. In all cases, the  
output is switched ON by an active high input level. Compared  
to their predecessor devices, the UDN2987A and UDN2987LW,  
the UDN2987A-6 and UDN2987LW-6 have a significantly  
faster TPHL (200 ns typical) and a lower driver supply voltage  
rating (4.75 V), which allows the use of 5 V logic.

The UDN2987A-6 is supplied in a 20-pin dual in-line plastic  
(DIP) package; the UDN2987LW-6 is supplied in a 20-lead  
small-outline (SOIC-W) plastic package. The Pb (lead) free  
versions have 100% matte-tin leadframe plating.
