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 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.

UDN2981A thru UDN2984A

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

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.

GND

V_S

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.

Dwg. No. A-10, 243

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 and UDN2984LW only) indicates an 18-

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.
