Fast GTLP Backplanes With the GTLPH1655
LVTTL Output Characteristics
The output characteristics of the LVTTL output side of the SN74GTLPH1655 are shown in
Figure 20, recorded with a supply voltage V
CC
= 3.3 V. The output resistance for the low state is
around 10 , and in the case of the high state, a value of about 25 is typical.
