RATING AND CHARACTERISTIC CURVES FOR SMDA05C-8 THRU SMDA24C-8
*Application note: Due to the topology of the SMDA array the V
RWM
and V
(BR)
specifications also
apply to the differential voltage between any two data line pins. Hence the SMDA12C-8 is
designed to "see" a maximum voltage excursion of 6 volts between any two data lines.
