description/ordering information

The SN74CBT3384A provides ten bits of  
high-speed TTL-compatible bus switching. The  
low on-state resistance of the switch allows  
connections to be made with minimal propagation  
delay.

The device is organized as two 5-bit switches with  
separate output-enable (OE) inputs. When OE is  
low, the switch is on, and port A is connected to  
port B. When OE is high, the switch is open, and  
the high-impedance state exists between the two  
ports.

stg  
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.  
NOTES: 1. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.  
2. The package thermal impedance is calculated in accordance with JESD 51-7.

All typical values are at V = 5 V (unless otherwise noted), T = 25°C.  
This is the increase in supply current for each input that is at the specified TTL voltage level, rather than V or GND.  
Measured by the voltage drop between the A and B terminals at the indicated current through the switch. On-state resistance is determined by  
the lowest voltage of the two (A or B) terminals.

(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.
