Description  
• Buffered Inputs  
The ’AC245 and ’ACT245 are octal-bus transceivers that  
utilize Advanced CMOS Logic technology. They are non-

intended for two-way transmission from “A” bus to “B” bus or  
“B” bus to “A”. The logic level present on the direction input  
(DIR) determines the data direction. When the output enable  
input (OE) is HIGH, the outputs are in the high-impedance  
state.  
• Exceeds 2kV ESD Protection per MIL-STD-883,  
Method 3015

(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.

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.
