Sigh, on the robot-board mailing list we are all very familiar with the L293
 (and its
beefier TI counterpart the TI75510.(check the number, its from memory)) The
National part that Digikey sells DOES NOT have the snubber diode and so it is
an L293E replacement, not an L293D replacement. If you use the Nat'l part you
need an external snubber network. There is also the Nat'l semi LM18200 which
is more expensive but can handle more current.

Digi-Key has the LM18293N which is a pin-compatible replacement for the
L293D with a few improved specs. $4.73 in singles and $1.80 in hundreds.
