74*245-based motor driver


Posted on Nov 12, 2012

A simple, time-honored approach is to use one or more 74*245 chips (normally the 74AC245 is used for maximum current capability) to provide motor drive current. Here, each channel of drive power is provided by one or more buffer on the chip.

One of these chips can provide 8 individual drives, at up to 35 mA per channel (at least, this is the official number -- read on, and you`ll see you can get a bit more out of this chip...). If you need more current than one driver can provide, you ca
