Thanks for your help, everyone.

Well, the topic title *is* "SN754410 H-Bridge Driver" :)

The motors need to run in either direction.


Here is the datasheet for anyone interested:

I'm wanting to use the sn754410 to drive the two small BLDC motors in
this product: http://www.sparkfun.com/products/319 (a gearbox/motor
combination)

The diodes I purchased are 1N5819 Schottky diodes:

frequency operation," but they might not be fast enough?
