Components

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.

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.

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.

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 T

rating (4.75 V), which allows the use of 5 V logic.

(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.
