The SN74GTL16923 is an 18-bit registered bus
transceiver that provides LVTTL-to-GTL/GTL+ and
GTL/GTL+-to-LVTTL
signal-level
translation.
This
device is partitioned as two 9-bit transceivers with
individual output-enable controls and contains D-type
flip-flops for temporary storage of data flowing in
either direction. 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.
<br/>
The user has the flexibility of using this device at either GTL (V
TT = 1.2 V and VREF = 0.8 V) or the preferred
higher noise margin GTL+ (V
TT = 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. All inputs can be
driven from either 3.3-V or 5-V devices, which allows use in a mixed 3.3-V/5-V system environment. V
REF is the
reference input voltage for the B port.
