DESCRIPTION/ORDERING INFORMATION  
The SN74GTL1655 is  
low-output-impedance  
a
high-drive (100 mA),  
(12 Ω) 16-bit UBT™  
V
REF  
transceiver that provides LVTTL-to-GTL/GTL+ and  
GTL/GTL+-to-LVTTL signal-level translation. This  
device is partitioned as two 8-bit transceivers and  
combines D-type flip-flops and D-type latches to allow  
for transparent, latched, and clocked modes of data  
transfer similar to the '16501 function. This device  
provides an interface between cards operating at  
LVTTL logic levels and a backplane operating at  
GTL/GTL+ signal levels. Higher-speed operation is a  
direct result of the reduced 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.  
The user has the flexibility of using this device at either GTL (VTT = 1.2 V and VREF = 0.8 V) or the preferred  
higher noise margin GTL+ (VTT = 1.5 V and VREF = 1 V) signal levels. GTL+ is the Texas Instruments derivative  
of the Gunning Transceiver Logic (GTL) JEDEC standard JESD 8-3. The B port normally operates at GTL or  
GTL+ signal levels, while the A-port and control inputs are compatible with LVTTL logic levels, but are not 5-V  
tolerant. VREF is the reference input voltage for the B port.

Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
