Notes: 1. Transition is measured
±200 mV from steady voltage with output load (B). This parameter is
sampled and not 100% tested.
2. If the CS# or LB# or UB# low transition occurs simultaneously with the WE# low transition or
after the WE# transition, output remains a high impedance state.
3. WE# and/or CS# must be high during address transition time.
4. If CS#, OE#, LB# and UB# are low during this period, I/O pins are in the output state. Then the
data input signals of opposite phase to the outputs must not be applied to them.
5. t
AS is measured from the latest address transition to the latest of CS#, WE#, LB# or UB# going
low.
6. t
WR is measured from the earliest of CS#, WE#, LB# or UB# going high to the first address
transition.
7. A write occurs during the overlap of a low CS#, a low WE# and a low LB# or a low UB# (t
WP).
A
write begins at the latest transition among CS# going low, WE# going low and LB# going low or
UB# going low. A write ends at the earliest transition among CS# going high, WE# going high
and LB# going high or UB# going high.
8. t
CW is measured from the later of CS# going low to the end of write.
