High-Speed Switching NoiseThe SN74GTL1655 a high-drive (100 mA),
low-output-impedance (12Ω) 16-bit UBT™
transceiver that provides LVTTL-to-GTL/GTL+ and
GTL/GTL+-to-LVTTL translation. This
deviceis partitioned two 8-bit transceivers and
combines D-type flip-flops and D-type latchesto allow
for transparent, latched, and clocked modesof data
transfer similarto the '16501 function. This device
provides an interface between cards operating at
LVTTL logic levelsa backplane operatingat
GTL/GTL+ signal levels. Higher-speed operationisa
direct result of the output swing (<1 V),
reduced input threshold levels, and OEC™ circuitry.
The high drive is suitable for driving
double-terminated low-impedance backplanes using
incident-wave switching.
higher noise margin (VTT= 1.5V and VREF=1V) signal GTL+is the Texas Instruments derivative Gunning Transceiver Logic (GTL) JEDEC standard JESD TheB port normally operatesat GTLor levels, the A-port and control inputs are compatible with LVTTL logic levels, but are not 5-Vis the input voltagefor theB port.
