arduino - Can L293D be replaced with SN754410NE?




I have a circuit that is set up to run motors using an Arduino and an H-Bridge chip. It works fine with the L293D chip but when I replace it with the SN754110NE chip it stops working.


As far as I can tell, the pinouts for both chips are identical so I'm not sure what the problem is.


Does anyone know what are the differences that would make one chip work but not the other?

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
