DESCRIPTION/ORDERING INFORMATION
This single-bit noninverting bus transceiver uses two separate configurable power-supply rails. The
SN74AVC1T45 is optimized to operate with VCCA/VCCB set at 1.4 V to 3.6 V. It is operational with VCCA/VCCB as
low as 1.2 V. The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.2 V to 3.6 V. The
B port is designed to track VCCB. VCCB accepts any supply voltage from 1.2 V to 3.6 V. This allows for universal
low-voltage bidirectional translation between any of the 1.2-V, 1.5-V, 1.8-V, 2.5-V, and 3.3-V voltage nodes.

SCES530G – DECEMBER 2003 – REVISED JANUARY 2008
DESCRIPTION/ORDERING INFORMATION (CONTINUED)
The SN74AVC1T45 is designed for asynchronous communication between two data buses. The logic levels of
the direction-control (DIR) input activate either the B-port outputs or the A-port outputs. The device transmits data
from the A bus to the B bus when the B-port outputs are activated and from the B bus to the A bus when the
A-port outputs are activated. The input circuitry on both A and B ports always is active and must have a logic
HIGH or LOW level applied to prevent excess ICC and ICCZ.
The SN74AVC1T45 is designed so that the DIR input is powered by VCCA.
This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs,
preventing damaging current backflow through the device when it is powered down.
The VCC isolation feature ensures that if either VCC input is at GND, then both ports are in the high-impedance
state.
NanoFree™ package technology is a major breakthrough in IC packaging concepts, using the die as the
package.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating
conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
The input negative-voltage and output voltage ratings may be exceeded if the input and output current ratings are observed.
The output positive-voltage rating may be exceeded up to 4.6 V maximum if the output current ratings are observed.
The package thermal impedance is calculated in accordance with JESD 51-7.

Power-Up Considerations
A proper power-up sequence always should be followed to avoid excessive supply current, bus contention,
oscillations, or other anomalies. To guard against such power-up problems, take the following precautions:
1. Connect ground before any supply voltage is applied.
2. Power up VCCA.
3. VCCB can be ramped up along with or after VCCA.

APPLICATION INFORMATION
Figure 3 shows the SN74AVC1T45 being used in a bidirectional logic level-shifting application. Since the
SN74AVC1T45 does not have an output-enable (OE) pin, the system designer should take precautions to avoid
bus contention between SYSTEM-1 and SYSTEM-2 when changing directions.

DESCRIPTION

Figure 3. Bidirectional Logic Level-Shifting Application
Enable Times
Calculate the enable times for the SN74AVC1T45 using the following formulas:
• tPZH (DIR to A) = tPLZ (DIR to B) + tPLH (B to A)
• tPZL (DIR to A) = tPHZ (DIR to B) + tPHL (B to A)
• tPZH (DIR to B) = tPLZ (DIR to A) + tPLH (A to B)
• tPZL (DIR to B) = tPHZ (DIR to A) + tPHL (A to B)
In a bidirectional application, these enable times provide the maximum delay from the time the DIR bit is
switched until an output is expected. For example, if the SN74AVC1T45 initially is transmitting from A to B, then
the DIR bit is switched; the B port of the device must be disabled before presenting it with an input. After the B
port has been disabled, an input signal applied to it appears on the corresponding A port after the specified
propagation delay.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, modifications, enhancements, improvements,
and other changes to its products and services at any time and to discontinue any product or service without notice. Customers should
obtain the latest relevant information before placing orders and should verify that such information is current and complete. All products are
sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment.
TI warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with TI’s standard
warranty. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where
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,
or other TI intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information
published by TI regarding third-party products or services does not constitute a license from TI to use such products or services or a
warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual
property of the third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied
by all associated warranties, conditions, limitations, and notices. Reproduction of this information with alteration is an unfair and deceptive
business practice. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional
restrictions.
Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all
express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not
responsible or liable for any such statements.
TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably
be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing
such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and
acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products
and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be
provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in
such safety-critical applications.
TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are
specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military
specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at
the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use.
TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are
designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any non-designated
products in automotive applications, TI will not be responsible for any failure to meet such requirements.
