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.

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.

1Pb-based variants are being phased out of the product line. Some variants cited in this footnote are in production but have been
determined to be LAST TIME BUY or NOT FOR NEW DESIGN. This classification indicates that sale of this device is currently
restricted to existing customer applications. The variants should not be purchased for new design applications because
obsolescence in the near future is probable. Samples are no longer available. For LAST TIME BUY: status change: October 31,
2006. Deadline for receipt of LAST TIME BUY orders: April 27, 2007. These variants include: A2982ELW, A2982ELWTR,
A2982SLW, A2982SLWTR, UDN2981A, and UDN2982A. For NOT FOR NEW DESIGN: status change: May 1, 2006. These
variants include: UDN2982LW and UDN2982LWTR.

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.
All unused inputs must be connected to ground. Pulldown resistors (≈ 10 kΩ) are recommended for inputs that
are allowed to float while power is being applied to VS.
Negative current is defined as coming out of (sourcing) the specified device terminal.
* All inputs simultaneously.
