8-CHANNEL SOURCE DRIVERS

Recommended for high-side switching applications that benefit from

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.

UDN2981A

All devices may be used with 5 V logic systems — TTL, Schottky TTL,

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.

The suffix ‘A’ (all devices) indicates an 18-lead plastic dual in-line

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.

Note that the UDN2980A series (dual in-line

package) and UDN2980LW series (small-outline

IC package) are electrically identical and share a

common terminal number assignment.

The suffix ‘LW’ (UDN2982LW only) indicates an 18-lead surface-

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

wide-body SOIC package with improved thermal characteristics.

ABSOLUTE MAXIMUM RATINGS

The UDN2982A, UDN2982LW, and A2982SLW 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’.

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

100% matte-tin leadframe plating.
