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, and A2982SLW areelectrically interchangeable, will withstand a maximum output off voltage of50 V, and operate to a minimum of 5 V. All devices in this series integrateinput current limiting resistors and output transient suppression diodes, andare activated by an active high input.The suffix ‘A’ (all devices) indicates an 18-lead plastic dual in-linepackage with copper lead frame for optimum power dissipation. Undernormal 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 only) indicates an 18-lead surfacemountablewide-body SOIC package; the A2982SLW is provided in a 20-leadwide-body SOIC package with improved thermal characteristics.The UDN2982A, UDN2982LW and A2982SLW drivers are also availablefor operation over an extended temperature range to -40°C. To order,change the prefix ‘UDN’ to ‘UDQ’ or the suffix ‘SLW’ to ‘ELW’.FEATURES■■■■■TTL, DTL, PMOS, or CMOS Compatible Inputs500 mA Output Source Current CapabilityTransient-Protected OutputsOutput Breakdown Voltage to 80 VDIP or SOIC PackagingAlways order by complete part number, e.g., UDN2981A .Note that all devices are not available in all package styles.
