The SN74GTLP817 is a medium-drive fanout driver that provides LVTTL-to-GTLP and GTLP-to-LVTTL
signal-level translation. The device provides a high-speed interface between cards operating at LVTTL logic
levels and a backplane operating at GTLP signal levels. High-speed (about three times faster than standard TTL
or LVTTL) backplane operation is a direct result of GTLP reduced output swing (<1 V), reduced input threshold
levels, improved differential input, and OEC circuitry. The improved GTLP OEC circuitry minimizes bus settling
time and has been designed and tested using several backplane models. The medium drive allows incident-wave
switching in heavily loaded backplanes with equivalent load impedance down to 19
. BO1 and BO2 can be tied
together to drive an equivalent load impedance down to 11
.
GTLP is the Texas Instruments (TI) derivative of the Gunning Transceiver Logic (GTL) JEDEC standard
JESD 8-3. The ac specification of the SN74GTLP817 is given only at the preferred higher noise-margin GTLP,
but the user has the flexibility of using this device at either GTL (VTT = 1.2 V and VREF = 0.8 V) or GTLP
(VTT = 1.5 V and VREF = 1 V) signal levels.
Normally, the B port operates at GTLP signal levels. The A-port and control inputs operate at LVTTL logic levels,
but are 5-V tolerant and are compatible with TTL and 5-V CMOS inputs. VREF is the B-port differential input
reference voltage.
GNDT is the TTL output ground, while GNDG is the GTLP output ground, and both may be separated from each
other for a quieter device.
