DESCRIPTION  
A Dynamic Output Control (DOC™) circuit 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.

This 12-bit to 24-bit registered bus exchanger is operational at 1.2-V to 3.6-V VCC, but is designed specifically for  
1.65-V to 3.6-V VCC operation.  
The SN74AVC16269 is used in applications in which two separate ports must be multiplexed onto, or  
demultiplexed from, a single port. The device is particularly suitable as an interface between synchronous  
DRAMs and high-speed microprocessors.  
Data is stored in the internal B-port registers on the low-to-high transition of the clock (CLK) input when the  
appropriate clock-enable (CLKENA) inputs are low. Proper control of these inputs allows two sequential 12-bit  
words to be presented as a 24-bit word on the B port. For data transfer in the B-to-A direction, a single storage  
register is provided. The select (SEL) line selects 1B or 2B data for the A outputs. The register on the A output  
permits the fastest possible data transfer, thus extending the period during which the data is valid on the bus.  
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas  
Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

DESCRIPTION (CONTINUED)  
The control terminals are registered so that all transactions are synchronous with CLK. Data flow is controlled by  
the active-low output enables (OEA, OEB1, OEB2).  
To ensure the high-impedance state during power up or power down, a clock pulse should be applied as soon as  
possible, and OE 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. Due to OE being routed through a register, the active state of the  
outputs cannot be determined prior to the arrival of the first clock pulse.  
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 SN74AVC16269 is characterized for operation from –40°C to 85°C.

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)

IMPORTANT NOTICE  
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other  
changes to its semiconductor products and services per JESD46C and to discontinue any product or service per JESD48B. Buyers should  
obtain the latest relevant information before placing orders and should verify that such information is current and complete. All  
semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale supplied at the time  
of order acknowledgment.  
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms  
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary  
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily  
performed.  
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and  
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide  
adequate design and operating safeguards.  
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or  
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information  
published by TI regarding third-party products or services does not constitute a license 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 significant portions 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. TI is not responsible or liable for such altered  
documentation. Information of third parties may be subject to additional restrictions.  
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service  
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.  
TI is not responsible or liable for any such statements.  
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements  
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support  
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which  
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause  
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use  
of any TI components in safety-critical applications.  
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to  
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and  
requirements. Nonetheless, such components are subject to these terms.  
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties  
have executed a special agreement specifically governing such use.  
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in  
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components  
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and  
regulatory requirements in connection with such use.  
TI has specifically designated certain components which meet ISO/TS16949 requirements, mainly for automotive use. Components which  
have not been so designated are neither designed nor intended for automotive use; and TI will not be responsible for any failure of such  
components to meet such requirements.
