ABSOLUTE MAXIMUM RATINGS
If Military/Aerospace specified devices are required, please
contact the National Semiconductor Sales Office/Distribu-
tors for availability and specifications.
contact the National Semiconductor Sales Office/Distribu-
tors for availability and specifications.
Note: Absolute maximum ratings indicate limits beyond
which damage to the device may occur. DC and AC electri-
cal specifications are not ensured when operating the de-
vice at absolute maximum ratings. * The latch-up tolerance
on Access Bus pins 14 and 15 exceeds 150mA.
