Unless specified: V
NOTES:
(1) Low duty cycle pulse testing with Kelvin connections required.
(2) V
(3) Defined as the input to output differential at which the output voltage drops 100mV below the value measured
at a differential of 1V. Not measurable on 1.5V and 1.8V parts due to minimum V
(4) Guaranteed by design.
