T iming specifications in
bold
print are 100% production tested. All other times are sample tested at +25
°
C to ensure compliance. All input signals are specified with
tr = tf = 5 ns (10% to 90% of 5 V) and timed from a voltage level of 1.6 V.

t

is measured with the load circuit of Figure 2 and defined as the time required for an output to cross 0.8 V or 2.4 V.
3
t
is derived from the measured time taken by the data outputs to change by 0.5 V when loaded with the circuit of Figure 2. T he measured number is then extrapo-
lated back to remove the effects of charging the 50 pF capacitor. T his means that the time, t

, quoted in the timing characteristics is the true bus relinquish time of
the part and as such is independent of external bus loading capacitances.

*Stresses above those listed under “Absolute Maximum Ratings” may cause
permanent damage to the device. T his is a stress rating only and functional
operation of the device at these or any other conditions above those listed in the
operational sections of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.
WARNING!
ESD SENSITIVE DEVICE
C AUT ION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the AD7880 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. T herefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
