We are trying to figure out if it would be acceptable to drive a MOSFET at a frequency of 20kHz using one of the output of a 74AHC244. We have captured the current waveforms during turn-on and turn-off, waveforms attached.
While the RMS is well within the Io spec. of table7 of the datasheet (“Limiting values”), the instantaneous current goes over the limit. I was wondering if the Io spec. refers to continuous current draw only or if it represent max. instantaneous current as well.
Would the following patterns present a reliability issue for the device if repeated continuously at a frequency of 20kHz.

Doug
