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.
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.
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.
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.
The UDN2982A, UDN2982LW, A2982SLW, UDN2984A,
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’.

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.

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