DESCRIPTION  
This 16-bit (dual-octal) noninverting bus transceiver uses two separate configurable power-supply rails. The  
A port is designed to track VCCA. VCCA accepts any supply voltage from 1.4 V to 3.6 V. The B port is designed to  
track VCCB. VCCB accepts any supply voltage from 1.4 V to 3.6 V. This allows for universal low-voltage  
bidirectional translation between any of the 1.5-V, 1.8-V, 2.5-V, and 3.3-V voltage nodes.  
The SN74AVCB164245 is designed for asynchronous communication between data buses. The device transmits  
data from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the  
direction-control (DIR) input. The output-enable (OE) input can be used to disable the outputs so the buses are  
effectively isolated.  
The SN74AVCB164245 is designed so that the control pins (1DIR, 2DIR, 1OE, and 2OE) are supplied by VCCB  
.
To ensure the high-impedance state during power up or power down, OE should be tied to VCCB through a pullup  
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.  
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. If either VCC input is at GND,  
both ports are in the high-impedance state.

(1) 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.  
(2) The input and output negative-voltage ratings may be exceeded if the input and output current ratings are observed.  
(3) The output positive-voltage rating may be exceeded up to 4.6 V maximum if the output current rating is observed.  
(4) The package thermal impedance is calculated in accordance with JESD 51-7.

Output Description  
The DOC™ circuitry is implemented, which, during the transition, initially lowers the output impedance to  
effectively drive the load and, subsequently, raises the impedance to reduce noise. Figure 1 shows typical VOL vs  
IOL and VOH vs IOH curves to illustrate the output impedance and drive capability of the circuit. At the beginning of  
the signal transition, the DOC circuit provides a maximum dynamic drive that is equivalent to a high-drive  
standard-output device. For more information, refer to the TI application reports, AVC Logic Family Technology  
and Applications, literature number SCEA006, and Dynamic Output Control (DOC™) Circuitry Technology and  
Applications, literature number SCEA009.

(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.

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

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
