Note 3: All devices are 100% production tested at T
A
= +70°C. All temperature limits are guaranteed by design.
Note 4: Guaranteed by design.
Note 5: Rise and fall times are measured using 20% and 80% levels.
Note 6: DJ measured using K28.5 pattern; RJ measured using K28.7 pattern.
Note 7: Total time for OOB detection circuit to enable/squelch the output.
