So today I finally started messing around with my SN754410, and I get it configured in a basic configuration (VDD1 5VDC, VDD2 3.6VDC) with the enables high and the grounds grounded. I have a LED with resistor on outputs 1 and 2 and without having anything on the inputs it is being pulled high. I know that a pulldown resistor will work but I was unsure of what the value would be, to prevent damage to the SN754410 if it was too low. I was thinking a 10K-100k?
