I
(commercial) = 115 mA + [(f - 12.5) 2 mA/MHz] for
f > 12.5 MHz
where f = the larger of the write or read
operating frequency.
I
(military) = 145 mA + [(f - 12.5) 2 mA/MHz] for
f > 12.5 MHz
where f = the larger of the write or read
operating frequency.
For test purposes, not more than one output at a time should be shorted. Short circuit test duration should not exceed 30 seconds.
Tested initially and after any design or process changes that may affect these parameters.
