I'm having difficulty finding a surface-mount replacement for the venerable ULN2803 (octal Darlington driver, 50V max, 500mA per driver, clamp diodes included). The application is low-speed stepper motor driving. I found the Texas Instruments ULN2803ADWR, but the documentation for it has me thoroughly confused. Digi-Key says it's an 18 SOIC but has no drawing or datasheet. The datasheet from TI shows a DIP package in both the pinout and mech drawings, but the description table shows "SOIC (DW)". Going to TI's packaging info page at <http://www.ti.com/sc/docs/psheets/mechanic/D.htm> shows they don't even have an 18-SOIC package! Can anyone clarify the actual dimensions of TI's part? I don't want to make boards with the wrong land pattern.. been there, done that. Or can someone suggest a replacement? I'm actually only switching about 110mA of load but the extra is nice to have; I don't want to go below 250mA per channel capability.
