The SN74GTLPH16945 is a medium-drive, 16-bit
bustransceiverthatprovidesLVTTL-to-GTLPand
GTLP-to-LVTTL signal-level translation. It is
partitioned as two 8-bit transceivers. 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’s reduced output swing
(<1 V), reduced input threshold levels, improved differential input, OEC circuitry, and TI-OPC circuitry.
Improved GTLP OEC and TI-OPC circuits minimize bus-settling time and have 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 Ω.
GTLP is the Texas Instruments derivative of the Gunning Transceiver Logic (GTL) JEDEC standard JESD 8-3.
The ac specification of the SN74GTLPH16945 is given only at the preferred higher noise margin GTLP, but the
user has the flexibility of using this device at either GTL (V = 1.2 V and V
= 0.8 V) or GTLP (V = 1.5 V

description (continued)
This device is fully specified for live-insertion applications using I , power-up 3-state, and BIAS V . The I
off
off
CC
circuitry disables the outputs, preventing damaging current backflow through the device when it is powered
down. The power-up 3-state circuitry places the outputs in the high-impedance state during power up and power
down, which prevents driver conflict. The BIAS V
circuitry precharges and preconditions the B-port
CC
input/output connections, preventing disturbance of active data on the backplane during card insertion or
removal, and permits true live-insertion capability.
This GTLP device features TI-OPC circuitry, which actively limits overshoot caused by improperly terminated
backplanes, unevenly distributed cards, or empty slots during low-to-high signal transitions. This improves
signal integrity, which allows adequate noise margin to be maintained at higher frequencies.
Active bus-hold circuitry holds unused or undriven LVTTL data inputs at a valid logic state. Use of pullup or
pulldown resistors with the bus-hold circuitry is not recommended.
When V
is between 0 and 1.5 V, the device is in the high-impedance state during power up or power down.
CC
However, to ensure the high-impedance state above 1.5 V, the output-enable (OE) input should be tied to V
CC
through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of
the driver.

16-BIT LVTTL-TO-GTLP BUS TRANSCEIVER
SCES292D – OCTOBER 1999 – REVISED NOVEMBER 2001
functional description
The SN74GTLPH16945 is a medium-drive (50 mA), 16-bit bus transceiver partitioned as two 8-bit segments
and is designed for asynchronous communication between data buses. The device transmits data from the
A port to the B port or from the B port to the A port, depending on the logic level at the direction-control (DIR)
input. OE can be used to disable the device so the buses are effectively isolated. Data polarity is noninverting.
For A-to-B data flow, when OE is low and DIR is high, the B outputs take on the logic value of the A inputs. When
OE is high, the outputs are in the high-impedance state.
The data flow for B to A is similar to that of A to B, except OE and DIR are low.

DISTRIBUTED-LOAD BACKPLANE SWITCHING CHARACTERISTICS
The preceding switching characteristics table shows the switching characteristics of the device into a lumped load
(Figure 1). However, the designer’s backplane application probably is a distributed load. The physical representation
is shown in Figure 2. This backplane, or distributed load, can be approximated closely to a resistor inductance
capacitance (RLC) circuit, as shown in Figure 3. This device has been designed for optimum performance in this RLC
circuit. The following switching characteristics table shows the switching characteristics of the device into the RLC
load, to help the designer better understand the performance of the GTLP device in this typical backplane. See
www.ti.com/sc/gtlp for more information.

(1) The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in
a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
(2)
Eco Plan - May not be currently available - please check http://www.ti.com/productcontent for the latest availability information and additional
product content details.
None: Not yet available Lead (Pb-Free).
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Green (RoHS & no Sb/Br): TI defines "Green" to mean "Pb-Free" and in addition, uses package materials that do not contain halogens,
including bromine (Br) or antimony (Sb) above 0.1% of total product weight.
(3)
MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDECindustry standard classifications, and peak solder
temperature.
