• Manufacturer Part Number: IDT70V9289L12PF
• Description: HIGH-SPEED 3.3V 64K x18/x16 SYNCHRONOUS PIPELINED DUAL-PORT STATIC RAM
• Manufacturer: IDT [Integrated Device Technology]

Timing Waveform of Read Cycle for
Flow-Through Output (FT/PIPE
Timing Waveform of Read Cycle for Pipelined Operation
(FT/PIPE
NOTES:
1. Transition is measured 0mV from Low or High-impedance voltage with the Output Test Load (Figure 2).
2. OE is asynchronously controlled; all other inputs are synchronous to the rising clock edge.
3. ADS = V
4. The output is disabled (High-Impedance state) by CE
5. Addresses do not have to be accessed sequentially since ADS = V
6. If UB or LB was HIGH, then the Upper Byte and/or Lower Byte of DATA
7. "X' here denotes Left or Right port. The diagram is with respect to that port.
