WRITE CYCLE AC TIMING CHARACTERISTICS (1)
(1) Test conditions: input switching levels VIL/VIH=0.5V/VDD-0.5V (CMOS), VIL/VIH=0V/3V (TTL), input rise and fall times <1 ns/V, input and
(2) Typical operating conditions: VDD=5.0 V, TA=25°C, pre-radiation.
(3) Worst case operating conditions: VDD=4.5 V to 5.5 V, -55 to 125°C, post total dose at 25°C.
(4) TAVAVW = TWLWH + TWHWL.
