DESCRIPTION/ORDERING INFORMATION
The SN74GTLPH3245 is a high-drive, 32-bit bus transceiver that provides LVTTL-to-GTLP and GTLP-to-LVTTL
signal-level translation. It is partitioned as four 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 LVTTL or TTL) 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 high drive allows incident-wave switching in heavily loaded
backplanes with equivalent load impedance down to 11 Ω.
GTLP is the Texas Instruments (TI™) derivative of the Gunning Transceiver Logic (GTL) JEDEC standard
JESD 8-3. The ac specification of the SN74GTLPH3245 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.
This device is fully specified for live-insertion applications using Ioff, power-up 3-state, and BIAS VCC. The Ioff
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 VCC circuitry precharges and preconditions the B-port 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.
High-drive GTLP backplane interface devices feature adjustable edge-rate control (ERC). Changing the ERC
input voltage between GND and VCC adjusts the B-port output rise and fall times. This allows the designer to
optimize system data-transfer rate and signal integrity to the backplane load.
Active bus-hold circuitry is provided to hold 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 VCC is between 0 and 1.5 V, the device is in the high-impedance state during power up or power down.
However, to ensure the high-impedance state above 1.5 V, the output-enable (OE) input should be tied to VCC
through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the
driver.

FUNCTIONAL DESCRIPTION
The SN74GTLPH3245 is a high-drive (100-mA), 32-bit bus transceiver partitioned in four 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 effectively are 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.

(1) All unused inputs of the device must be held at VCC or GND to ensure proper device operation. Refer to the TI application report,
Implications of Slow or Floating CMOS Inputs, literature number SCBA004.
(2) Proper connection sequence for use of the B-port I/O precharge feature is GND and BIAS VCC = 3.3 V first, I/O second, and VCC = 3.3 V
last, because the BIAS VCC precharge circuitry is disabled when any VCC pin is connected. The control and VREF inputs can be
connected anytime, but normally are connected during the I/O stage. If B-port precharge is not required, any connection sequence is
acceptable, but generally, GND is connected first.
(3) VTT and RTT can be adjusted to accommodate backplane impedances if the dc recommended IOL ratings are not exceeded.
(4) VREF can be adjusted to optimize noise margins, but normally is two-thirds VTT. TI-OPC circuitry is enabled in the A-to-B direction and is
activated when VTT > 0.7 V above VREF. If operated in the A-to-B direction, VREF should be set to within 0.6 V of VTT to minimize current
drain.

(1) All typical values are at VCC = 3.3 V, TA = 25°C.
(2) For I/O ports, the parameter II includes the off-state output leakage current.
(3) The bus-hold circuit can sink at least the minimum low sustaining current at VILmax. IBHL should be measured after lowering VIN to GND
and then raising it to VILmax.
(4) The bus-hold circuit can source at least the minimum high sustaining current at VIHmin. IBHH should be measured after raising VIN to VCC
and then lowering it to VIHmin.
(5) An external driver must source at least IBHLO to switch this node from low to high.
(6) An external driver must sink at least IBHHO to switch this node from high to low.
(7) This is the increase in supply current for each input that is at the specified TTL voltage level rather than VCC or GND.

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 - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability
information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
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.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)
(3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.

mandated by government requirements, testing of all parameters of each product is not necessarily performed.
TI assumes no liability for applications assistance or customer product design. Customers are responsible for their products and
applications using TI components. To minimize the risks associated with customer products and applications, customers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask work right,
