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.
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
www.DataSheet4U.com
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 over-current
fault circuit will protect the device from short-circuits to ground
with supply voltages of up to 30 V.
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.

*Pb-based variants are being phased out of the product line. The variants cited in this footnote are in production
but have been determined to be LAST TIME BUY. This classification indicates that sale of this device is cur-
rently restricted to existing customer applications. The variants should not be purchased for new design applica-
tions because obsolescence in the near future is probable. Samples are no longer available. Status change:
October 31, 2006. Deadline for receipt fo LAST TIME BUY orders: April 27, 2007. These variants include:
UDN2987A-6, UDN2987LW-6, and UDN2987LWTR-6.
