question on a h-bridge circuit I found on this page

Hello everyone,

well, I´m pretty new to this community and I hope this post is not too dumb in your eyes. I´m more at home when it comes to computers but as soon as I get into contact with circuits and means to make a computer sense the "real world", I thought about giving it the opportunity to drive around next to other actions. In fact I´m trying my best to deal with microcontrollers and learn by doing.

Schottky diode bridge IC for L298N?

Hi all!

Noob question: I'm using the L298N dual full H-bridge to drive my robot's 4 motors, can someone please give me the name of a chip that contains schottky diodes in a bridge configuration, so I can use it on the outputs to block back EMF? Sparkfun does the same on their boards: http://www.sparkfun.com/datasheets/Robotics/ROB-09571-Serial%20Controlled%20Dual%20Motor%20Driver%20-%20v11.pdf

I know that there are such ICs since I recall a friend using a 16-pin DIP in a similar occasion, but I can't remember it's name. I think it started with "L".
