ELECTRICAL CHARACTERISTICS (continued)
(VCC = +5V Q10%, TA = TMIN to TMAX, unless otherwise noted. Typical values are at VCC = +5V, TA = +25NC.) (Note 2)
Note 2: Devices are production tested at TA = +25NC. Specifications over temperature limits are guaranteed by design.
Note 3: VODPP is the difference in VOD, with the DI at high and DI at low.
Note 4: DVOD and DVOC are the changes in |VOD| and |VOC|, respectively, with the DI at high and DI at low.
Note 5: The short-circuit output current applies to peak current just prior to foldback current limiting; the short-circuit foldback out-
put current applies during current limiting to allow a recovery from bus contention.
Note 6: Shutdown is enabled by bringing RE high and DE low. If the enable inputs are in this state for less than 50ns, the device
is guaranteed not to enter shutdown. If the enable inputs are in this state for at least 800ns, the device is guaranteed to
have entered shutdown.
Note 7: Capacitive load includes test probe and fixture capacitance.
Note 8: Guaranteed by characterization; not production tested.
