Recommended for high-side switching applications that benefit fromseparate logic and load grounds, these devices encompass load supplyvoltages to 80 V and output currents to -500 mA. These 8-channel sourcedrivers are useful for interfacing between low-level logic and high-currentloads. Typical loads include relays, solenoids, lamps, stepper and/or servomotors, print hammers, and LEDs.

All devices may be used with 5 V logic systems — TTL, Schottky TTL,DTL, and 5 V CMOS. The UDN2981A, UDN2982A, UDN2982LW, andA2982SLW 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 limitingresistors and output transient suppression diodes, and are activated by anactive high input.

The suffix ‘A’ (all devices) indicates an 18-lead plastic dual in-linepackage with copper lead frame for optimum power dissipation. Under

normal operating conditions, these devices will sustain 120 mA continuouslyfor each of the eight outputs at an ambient temperature of +50°C and a supplyof 15 V.

The suffix ‘LW’ (UDN2982LW and UDN2984LW only) indicates an 18-lead surface-mountable wide-body SOIC package; the A2982SLW andA2984SLW are provided in a 20-lead wide-body SOIC package with im-proved thermal characteristics.

The UDN2982A, UDN2982LW, A2982SLW, UDN2984A,

UDN2984LW, and A2984SLW drivers are also available for operation overan extended temperature range to -40°C. To order, change the prefix ‘UDN’to ‘UDQ’ or the suffix ‘SLW’ to ‘ELW’.

NOTES:Turn-off delay is influenced by load conditions. Systems applications well below the specified output loading may require

timing considerations for some designs, i.e., multiplexed displays or when used in combination with sink drivers in a totempole configuration.

Negative current is defined as coming out of (sourcing) the specified device terminal.* All inputs simultaneously.
