NOTES:
1. These parameters are determined by device characterization, but are not
production tested.
2. 3dV references the interpolated capacitance when the input and output switch
from 0V to 3V or from 3V to 0V.
3. C
OUT also references CI/O.

NOTES:
1. "H" = V
IH, "L" = VIL, "X" = Don't Care.
2. CE
0, LB, UB, and OE = VIL; CE1 and R/W = VIH.
3. Outputs configured in Flow-Through Output mode; if outputs are in Pipelined mode the data out will be delayed by one cycle.
4. ADS and CNTRST are independent of all other signals including CE
0, CE1, UB and LB.
5. The address counter advances if CNTEN = V
IL on the rising edge of CLK, regardless of all other signals including CE0, CE1, UB and LB.
NOTES:
1. V
IL > -1.5V for pulse width less than 10 ns.
2. V
TERM must not exceed VDD +0.3V.
NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may
cause permanent damage to the device. This is a stress rating only and functional
operation of the device at these or any other conditions above those indicated
in the operational sections of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect reliability.
2. V
TERM must not exceed VDD +0.3V for more than 25% of the cycle time or 10ns
maximum, and is limited to
< 20mA for the period of VTERM > VDD + 0.3V.
3. Ambient Temperature Under DC Bias. No AC Conditions. Chip Deselected.
NOTE:
1. This is the parameter T
A. This is the "instant on" case temperature.
