Note:
SN74GTL1655 devices were used on the receiver cards. The
SN74GTLPH1655 was in development and initial preproduction samples
were used for the driver cards, but insufficient quantities were available for
the receiver cards. The SN74GTL1655 and SN74GTLPH1655 are identical,
except for the B-port output edge rate (slew) and B-port C
io
. Because the
GTLP signals only are received by the receiver cards, it is essentially
immaterial which devices are used on the receiver cards, because both have
the same differential input (except for the difference in B-port C
io
, which is
6 pF typical and 8 pF maximum for the SN74GTL1655, and 8.5 pF typical and
10.5 pF maximum for the SN74GTLPH1655). GTLP devices have a larger
B-port C
io
, because a larger transistor and ESD cell is required by the newer
CMOS process.
