l293D SN754410

L293/SN754410 h-bridge schmatic



I am a technology education teacher who teaches an industrial design course. This previous year we used the L293D chip to make a motor shield that works withe Arduino. The schematic that i was using works very well with the L293D chip but will not work with the L293 or the SN754410. Attached is a schematic of my motor shield with diode protection. i hope the diodes allow me to use the L293 and the SN754410. If any one is familiar with this sort of motor shield i would love to have my schematic looked over and any possible suggestions made.
