• Manufacturer: Integrated Device Technology

IDT7130SA/LA AND IDT7140SA/LA
HIGH-SPEED 1K x 8 DUAL-PORT STATIC RAM WITH INTERRUPTS
TIMING WAVEFORM OF READ CYCLE NO. 2, EITHER SIDE
AC ELECTRICAL CHARACTERISTICS OVER THE
OPERATING TEMPERATURE AND SUPPLY VOLTAGE RANGE
NOTES:
1. Transition is measured 500mV from Low or High-impedance voltage with Output Test Load (Figure 2). This parameter is guaranteed by
2. 0 C to +70 C temperature range only, PLCC and TQFP packages.
3. For MASTER/SLAVE combination, t
4. If
5. “X” in part numbers indicates power rating (SA or LA).
6. Not available in DIP packages.
NOTES:
1. Timing depends on which signal is asserted last,
2. Timing depends on which signal is deaserted first,
3. R/
4. Start of valid data depends on which timing becomes effective last t
