High-Speed 1K x 8 Dual-Port Static SRAM
Military, Industrial and Commercial Temperature Ranges
Timing Waveform of Read Cycle No. 2, Either Side(3)
NOTES:
1. Timing depends on which signal is asserted last,
OE or CE.
2. Timing depends on which signal is deaserted first,
OE or CE.
3. R/
W = VIH and OE = VIL, and the address is valid prior to or coincidental with CE transition LOW.
4.
Start of valid data depends on which timing becomes effective last tAOE, tACE, tAA, and tBDD.

NOTES:
1. R/
W = VIH, CE = VIL, and is OE = VIL. Address is valid prior to the coincidental with CE transition LOW.
2. tBDD delay is required only in the case where the opposite port is completing a write operation to the same the address location. For simultaneous read operations,
BUSY has no relationship to valid output data.
3. Start of valid data depends on which timing becomes effective last tAOE, tACE, tAA, and tBDD.
