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. The suffix ‘LW’ (UDN2982LW only) indicates an 18-lead surfacemountable wide-body SOIC package; the A2982SLW is provided in a 20-lead wide-body SOIC package with improved thermal characteristics. 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.

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. 21.5 115 Northeast Cutoff, Box 15036 Worcester, Massachusetts 01615-0036 (508) 853-5000 2981 AND 2982 8-CHANNEL SOURCE DRIVERS One of Eight Drivers V5 9 20 K 7.2 K 3K INP UT OUT P UT 1.5 K G R OUND Dwg.

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. † Complete part number includes a prefix (A or UDN) and a suffix (A or SLW) as follows: UDN2981A, UDN2982A, UDN2982LW, or A2982SLW. www.allegromicro.com 3 2981 AND 2982 8-CHANNEL SOURCE DRIVERS TEST FIGURES Figure 1 Figure 2 VS VS V Figure 3 V V CE S I IN mA mA OPEN I OUT V VIN µA IN V IN I CEX Dwg.
