separate logic and load grounds, these devices encompass load supply

voltages to 80 V and output currents to -500 mA. These 8-channel source

drivers are useful for interfacing between low-level logic and high-current

loads. Typical loads include relays, solenoids, lamps, stepper and/or servo

motors, print hammers, and LEDs.

DTL, and 5 V CMOS. The UDN2981A, UDN2982A, UDN2982LW, and

A2982SLW are electrically interchangeable, will withstand a maximum

output off voltage of 50 V, and operate to a minimum of 5 V; the UDN2983A,

UDN2984A, UDN2984LW, and A2984SLW drivers are electrically inter-

changeable, will withstand an output voltage of 80 V, and operate to a

minimum of 35 V. All devices in this series integrate input current limiting

resistors and output transient suppression diodes, and are activated by an

active high input.

package with copper lead frame for optimum power dissipation. Under

normal operating conditions, these devices will sustain 120 mA continuously

for each of the eight outputs at an ambient temperature of +50°C and a supply

of 15 V.

lead surface-mountable wide-body SOIC package; the A2982SLW and

A2984SLW are provided in a 20-lead wide-body SOIC package with im-

proved thermal characteristics.

UDN2984LW, and A2984SLW drivers are also available for operation over

an extended temperature range to -40°C. To order, change the prefix ‘UDN’

to ‘UDQ’ or the suffix ‘SLW’ to ‘ELW’.
