Gate drive pin of PWM controller IC needs protection diode?

The 1241 is transistor logic.
The 3421 is MOSFET logic. (internal diode)

I did not answer the question.
Keep the IC to Gate trace short.
 
The LM3421 datasheet doesn't actually say that it is MOSFET based though?
As far as we know, the LM3421 could be mosfet based, bjt based, or BiCMOS based?
Also, isn't BJT based IC's more resilient to static electricity damage?

The inputs of MOS-logis has static problems. I think the outputs are not.
datasheet says that the gate drive pin needs a Schottky protection diode
We are talking about high current output drivers.
I think the problem is ring in the IC to Gate trace. Some people have 4 inches of trace and it will ring and exceed one diode of kick back voltage. Because the current (edge current) is 2A, or so, the ring back has some power in it.
