separate logic and load grounds, these devices encompass load supply

voltages to 50 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, and A2982SLW are

electrically interchangeable, will withstand a maximum output off voltage of

50 V, and operate to a minimum of 5 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.

mountable wide-body SOIC package; the A2982SLW is provided in a 20-lead

wide-body SOIC package with improved thermal characteristics.

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’.

These packages are available in Pb (lead) free variants (suffix ‘-T’), with

100% matte-tin leadframe plating.

FEATURES

Always order by complete part number, e.g., UDN2981A-T .

Note that all devices are not available in all package styles.
