Hello can any one tell me why im getting no outputs to motors when using sn754410ne, however all is fine when using l293d, have i missed something. My understanding was that the 754410 is a direct pin for pin replacement to l293d.
Im driving 2 motors using dual hbridge.
Can anyone enlighten me.

Thanks in advance.
