NOTES: (1) All input signals are specified with rise and fall times of 5ns, tR = tF = 5ns (10% to 90% of DVDD), and timed from a voltage level of (VIL + VIH) /2. (2)
See timing diagram, below. (3) BYTE is asynchronous; when BYTE is 0, bits 15 through 0 appear at DB15-DB0. When BYTE is 1, bits 15 through 8 appear on
DB7-DB0. RD may remain LOW between changes in BYTE.
TIMING CHARACTERISTICS(1)(2)
All specifications typical at –40
°C to +85°C, +DV
DD = +5V.
