AC Electrical Characteristics Over the

Operating Temperature and Supply Voltage Range(4,5)

NOTES:

1. Transition is measured ±500mV from Low or High-impedance voltage with Output Test Load (Figure 2).

2. This parameter is guaranteed by device characterization, but is not production tested.

3. To access RAM, CE = VIL, UB or LB = VIL, and SEM = VIH. To access semaphore, CE = VIH or UB & LB = VIH, and SEM = VIL.

4. 'X' in part numbers indicates power rating (S or L).

5. Industrial temperature: for specific speeds, packages and powers contact your sales office.

NOTES:

1. Timing depends on which signal is asserted last, OE, CE, LB, or UB.

2. Timing depends on which signal is de-asserted first, CE, OE, LB, or UB.

3. tBDD delay is required only in case where opposite port is completing a write operation to the same address location for simultaneous read operations BUSY has

no relation to valid output data.

4. Start of valid data depends on which timing becomes effective last

tABE, tAOE, tACE, tAA or tBDD.

5. SEM = VIH.
