NOTES:
1. At f = fMAX, address and control lines (except Output Enable) are cycling at the maximum frequency clock cycle of 1/tCYC, using "AC TEST CONDITIONS" at input
levels of GND to 3V.
2. f = 0 means no address, clock, or control lines change. Applies only to input at CMOS level standby.
3. Port "A" may be either left or right port. Port "B" is the opposite from port "A".
4. VDD = 3.3V, TA = 25°C for Typ, and are not production tested. IDD DC(f=0) = 90mA (Typ).
5. CEX = VIL means CE0X = VIL and CE1X = VIH
CEX = VIH means CE0X = VIH or CE1X = VIL
CEX < 0.2V means CE0X < 0.2V and CE1X > VDD - 0.2V
CEX > VDD - 0.2V means CE0X > VCC - 0.2V or CE1X < 0.2V
"X" represents "L" for left port or "R" for right port.

NOTES:
1. Transition is measured 0mV from Low or High-impedance voltage with the Output Test Load (Figure 2). This parameter is guaranteed by device characteriza-
tion, but is not production tested.
2. The Pipelined output parameters (tCYC2, tCD2) apply to either or both the Left and Right ports when FT/PIPE = VIH. Flow-through parameters (tCYC1, tCD1) apply
when FT/PIPE = VIL for that port.
3. All input signals are synchronous with respect to the clock except for the asynchronous Output Enable (OE), FT/PIPER, and FT/PIPEL.

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 = VIL and CNTRST = VIH.
4. The output is disabled (High-Impedance state) by CE0 = VIH, CE1 = VIL, UB = VIH, or LB = VIH following the next rising edge of the clock. Refer to Truth Table 1.
5. Addresses do not have to be accessed sequentially since ADS = VIL constantly loads the address on the rising edge of the CLK; numbers
are for reference use only.
6. If UB or LB was HIGH, then the Upper Byte and/or Lower Byte of DATAOUT for Qn + 2 would be disabled (High-Impedance state).
7. "X' here denotes Left or Right port. The diagram is with respect to that port.

NOTES:
1. B1 Represents Bank #1; B2 Represents Bank #2. Each Bank consists of one IDT70V9389 or IDT70V9289 for this waveform, and are setup for depth expansion
in this example. ADDRESS(B1) = ADDRESS(B2) in this situation.
2. UB, LB, OE, and ADS = VIL; CE1(B1), CE1(B2), R/W and CNTRST = VIH.
3. Transition is measured 0mV from Low or High-impedance voltage with the Output Test Load (Figure 2).
4. CE0, UB, LB, and ADS = VIL; CE1 and CNTRST = VIH.
5. OE = VIL for the Right Port, which is being read from. OE = VIH for the Left Port, which is being written to.
6. If tCCS < maximum specified, then data from right port READ is not valid until the maximum specified for tCWDD.
If tCCS > maximum specified, then data from right port READ is not valid until tCCS + tCD1. tCWDD does not apply in this case.
7. All timing is the same for both Left and Right ports. Port "A" may be either Left or Right port. Port "B" is the opposite from Port "A".

3. The "Internal Address" is equal to the "External Address" when ADS = VIL and equals the counter output when ADS = VIH.
4. Addresses do not have to be accessed sequentially since ADS = VIL constantly loads the address on the rising edge of the CLK; numbers are for reference use only.
5. Output state (High, Low, or High-impedance) is determined by the previous cycle control signals.
6. No dead cycle exists during counter reset. A READ or WRITE cycle may be coincidental with the counter reset cycle. ADDR0 will be accessed. Extra cycles
are shown here simply for clarification.
7. CNTEN = VIL advances Internal Address from ‘An’ to ‘An +1’. The transition shown indicates the time required for the counter to advance.
The ‘An +1’ Address is written to during this cycle.
