I have a PWM signal that I want to control a heater (3 ohms) with a 36V source. My MOSFETS keep blowing using TC4427
I initially used a 74HC04 to drive the MOSFET gates. This was initially because I wanted 5V on the gate: by putting the pwm 3v3 through the 74HC04 and then re-inverting the pwm came out st 5V. I chose ...

Can one use a 32mA line driver with a source-series-terminated 50ohm transmission line and 3.3v VCC?
It appears that line drivers generally do not exceed 32mA of drive ability, at least not in the "recommended operating conditions" section.
At 3.3V VCC [to the driver chip, and hence signal ...
